19.09.2011 par Israel Defense Forces

 

23 ans après le lancement de son premier satellite de reconnaissance Ofeq 1, Yehiel Shalev, le Chef du département des Satellites  de l’Agence Spatiale Israélienne revient sur les dernières innovations et nous introduit dans son usine.

 

« Nous avons développé de nouveaux systèmes dans trois domaines différents. Il s’agit essentiellement des satellites d’observation électro-optiques, des satellites de communication notamment avec la série de satellites de communication AMOS  et des satellites de reconnaissance utilisés comme radars », a affirmé Shalev.

 

La construction et l’intégration d’un satellite peut prendre trois ans. Les salles de travail sont isolées, stériles et maintenues à une température constante, tout au long de l’année.

 

Au cours de la phase finale de développement, le satellite RAS (radar à synthèse d’ouverture) était enfin capable de recevoir les transmissions grâce à ses radars, et les changements climatiques sur Terre n’avaient donc aucun impact sur son efficacité. Il pourra ainsi recevoir des photos et transmettre des informations quelque soit le climat.

 

Presque deux fois plus grand que ses congénères, le satellite Amos 4 est le plus gros satellite de communication fabriqué par l’Industrie Aérospatiale Israélienne.

 

« Le satellite Amos est capable de mesurer le nombre de transpondeurs qu’il possède », a expliqué Shalev. Un transpondeur est un appareil automatique qui reçoit, amplifie et retransmet des signaux sur des fréquences différentes. « Après avoir été lancé, le satellite est censé peser 4.3 tonnes. »

 

Le satellite OpSat 3000 est un nouveau satellite d’observation. « Il s’agit d’une nouvelle génération de satellites d’observation dans la lignée du programme Ofeq, » nous explique Shalev. « Ce nouveau satellite fonctionnera à l’aide des technologies que nous avons mises au point ici-même, y compris des systèmes optiques et des systèmes de contrôle. Les photos produites seront plus précises et de qualité supérieure. »

 

Le nouveau satellite aura un télescope de diamètre plus large que l’Ofeq 9, ce qui lui permettra de prendre des photos de meilleure qualité. « Un télescope en couleurs sera prochainement ajouté aux satellites », a confirmé Shalev.

 

« Nous avons récemment commencé à travailler sur les micro et les nano-satellites. L’avantage est que ces satellites ne pèsent que quelques kilos et qu’ils sont très différents de ceux que nous avons produits jusqu’à présent. Au lieu d’utiliser un grand satellite dans le cadre d’une opération, nous pourrons utiliser une série de petits satellites. »

 

Les nano-satellites présentent également l’avantage d’être peu coûteux, car leur lancement implique un faible investissement financier puisque leur poids ne dépasse pas les dix kilogrammes.

 

Puisque les satellites ne peuvent pas être réparés après avoir été lancés, il est essentiel de s’assurer que chaque élément fonctionne parfaitement et que le satellite pourra résister aux changements environnementaux.

 

« Le bruit extrêmement fort produit par le lancement du satellite est responsable de vibrations très puissantes qui peuvent endommager significativement son fonctionnement mécanique et nous devons être certains que le système pourra résister à cette pression », nous explique Shalev.

 

« Chaque stade de développement est risqué et nécessite un investissement financier énorme. Nous mettons d’abord au point les modèles de tous les systèmes et nous testons chaque modèle séparément.  C’est le secret de notre réussite: chaque satellite qui a été lancé fonctionne parfaitement et ce depuis de nombreuses années ».

NRO's ability to fuse various streams of intelligence data - including image, signals and geolocation - into a single, usable result has increased by an order of magnitude, but is five orders of magnitude below where it needs to be.

 

Sep 19, 2011 by Karen Parrish (AFNS)

 

Washington DC -- The National Reconnaissance Office is 50 years old this month, but its mission of designing, building, launching and maintaining America's intelligence satellites is always future focused, its chief said yesterday.

 

Bruce A. Carlson, a retired Air Force general and NRO's director, told defense reporters here the office's current missions range from identifying roadside bombs in Afghanistan to tracking activities in China and North Korea.

 

The National Reconnaissance Office has launched six satellites in seven months, "the best we've done in about 25 years," the director said.

 

As recently as two years ago, more than 30 percent of the organization's programs were rated yellow or red for improper performance. All the NRO's major system acquisition programs are now in the green - delivering on schedule, on contract and on price, Carlson said.

 

Carlson said NRO's mission is getting more challenging because space is becoming increasingly congested where the satellites work.

 

"Other countries are launching a lot of stuff, and it's becoming more competitive," he said. "We all have to operate in the same space."

 

And it's no secret the Chinese are becoming more active in space, the director added. "That concerns us because we're not absolutely sure of their intent," he said.

 

NRO and Air Force Space Command have a joint space protection program, Carlson said, which is the "ace in the hole" should "somebody try to do something."

 

"We also use the space protection program to work around the congestion problem ... make sure we don't run into something else up there," he said.

 

China and Russia both contend with the United States for room in space, Carlson said.

 

In satellite surveillance as with night fighting, deep strike capabilities and special operations expertise, "they have to focus on our strengths," the director said.

 

China and Russia don't try to compete with U.S. capabilities, but to counter them, Carlson noted. "That's why we have a space protection program," he said.

 

China is a focus for his organization's surveillance efforts, as is North Korea, Carlson said.

 

"I remain concerned about [China's] intent and exactly what it is that I do not know," he said.

 

North Korea also works "really hard to deceive us," Carlson noted. "We work really hard to make sure we don't let them deceive us. So it's sort of a cat-and-mouse game. It's very serious for us."

 

The NRO's three main lines of business are imaging, signals collection and communications, the director said. The science and technology, or developmental and demonstration program, underlies all three, he added.

 

"We have a very active program to do our own technology," Carlson said. "We're the only organization in the government that does space reconnaissance ... and that takes some unique technologies."

 

NRO partners with the National Laboratories and the Defense Advanced Research Projects Agency in developing new capabilities, but some 60 percent of the equipment on the six recently launched satellites was developed in-house, he said.

 

Several other small satellites - less than about 1,000 pounds - are now in orbit demonstrating new technologies that NRO will roll into its existing surveillance systems, the director said.

 

For imaging reconnaissance, the NRO seeks to examine as many parts of the spectrum with as many instruments as possible, he said.

 

The goal is to "do sensing ... in the daytime, at night, in bad weather, good weather ... and sandstorms," he said.

 

Some of the signals collection satellites are "remarkably old," he said.

 

"Those satellites were designed to collect Soviet long-haul communications that dealt with the Cold War," he said. "Now they're collecting phone calls or push-to-talk radio signals out of the war zone."

 

NRO uses its communications satellites to relay image or signals data around the world and down to the ground for processing, then shunt the results back to where they're needed, Carlson said.

 

"Processing takes a lot of energy and [computer] capacity," he said. "We've got to do that on the ground; we can't afford to do it in space."

 

NRO's ability to fuse various streams of intelligence data - including image, signals and geolocation - into a single, usable result has increased by an order of magnitude, but is five orders of magnitude below where it needs to be, Carlson said.

 

"It's incredibly difficult to take a picture someplace and fuse it with signals intelligence, that you might have a million pieces of, and sort that all out and geolocate it rapidly," he said. "But in many cases we're able to do that ... in minutes or less."

 

One promising example of fusion is the "red dot" system, Carlson said, which pinpoints the signals emitted by roadside bombs set for electronic detonation.

 

"We do a lot of work to make sure that we know what those signals are, where they're coming from, and geolocate them," he said.

 

That data generates a red dot on displays in military vehicles or command posts to show high probability of an explosive, he added.

 

"I can't tell you exactly how we do that, but it's a pretty clever set of technologies," the director said. "What it has meant is that, even though we still have an unacceptable loss from [roadside bombs], we are catching a lot of them before they're detonated."

 

The system has been in place for approximately six months and has been about 80 percent effective, he added.

 

NRO was also "instrumental" to the NATO operation in Libya, ensuring the air campaign was successful, Carlson said.

 

The NRO feeds data to military commanders, he said, but it is also a key strategic asset, serving the National Security Agency and National Geospatial-Intelligence Agency.

 

There will always be competition between, for example, the information an analyst wants to assess foreign weapon systems and a combat commander's need to know where and how many cell phones are operating in a particular enemy area, the director noted.

 

Whether identifying insurgent behavior patterns or focusing on larger national security questions, Carlson said, "My job is to ... get the most out of a sensor."

 

There are only so many satellites in orbit, so NRO has an inclusive and responsive process to allocate its 24-hour capabilities, he said.

 

"What that allows us to do is very rapidly ... worldwide and throughout our architecture, tune those systems," he said.

 

An example is an aircraft bailout requiring a search-and-rescue effort, he said.

 

"We can, within a matter of seconds, turn an incredible number of our sensors on a specific area," he added.

 

Carlson said during NRO's next 50 years, the challenges are to do what it now does even better, and to develop more in-space capability.

 

"We know what we have to do - we have to provide the best, integrated intelligence in the world," he said. "Now, [we have to] do it faster and cheaper."

 

Space satellites have always focused downward, and now need to be able to look around and up as well, he said.

 

"Because space is more congested and more contested and more competitive ... we've got to build systems that continue to be much more adaptable," he said. "Space reconnaissance - that's my job."

Sep 16, 2011 by Amy Walker, PEO C3T Source : US Army ASDNews

 

Aberdeen Proving Ground, Md. - With more expansive satellite communications requirements, the Army is moving away from expensive commercial satellites and leveraging those of the U.S. military.

 

"The advantage is two-fold -- there is a big cost avoidance in utilizing military satellites, second the military requires us to be more efficient with the resources," said Lt. Col. Gregory Coile, product manager for Satellite Communications, or PdM SATCOM, assigned to the Army's Project Manager Warfighter Information Network-Tactical, which is known as PM WIN-T.

 

PM WIN-T is part of the Army's Program Executive Office Command, Control and Communications-Tactical, or PEO C3T.

 

Through its increased use of U.S. military satellites, the Army could potentially save millions. U.S. Army Central Command. or CENTCOM, alone is spending millions of dollars a year on commercial satellite use.

 

Without enough bandwidth to entirely avoid the use of commercial Ku band satellite frequencies, the Army plans to utilize military satellites whenever feasible, said Lynn Epperson, acting deputy for PdM SATCOM. To further this mission, PM WIN-T is certifying its earth satellite terminals with military Ka and X-band frequency capability to take advantage of the military's Wideband Global SATCOM, or WGS, satellites.

 

"Certifying commercial-off-the-shelf terminals may take some up-front funding and time but will be well worth the wait in the long run," said Marc Crudo, project lead for Deployable Ku Band Earth Terminals, or DKET.

 

With satellite terminal certification, the government is endorsing that the terminal meets Department of Defense efficiency standards to obtain and transmit the bandwidth to support the Army's requirements over military satellites. The certification verifies that the antenna and terminal perform within military specifications, do not interfere with other users and will not cause possible damage to the satellite.

 

The Ka and X band certification for the Army's Secure Internet Protocol Router/Non-secure Internet Protocol Router Access Point, or SIPR/NIPR SNAP, satellite terminals was completed in June. The certification testing for the larger-size DKET terminals was completed in Aug., and conditional Ka and X band DKET certification is expected by early Oct.

 

While SNAP satellite terminals are designed for use at small combat outposts, DKETs are geared for larger hub locations. From their respective ends of the spectrum, these capabilities support and complement the WIN-T network -- the backbone of Army battlefield communications.

 

"SNAPs are the spokes of the wheel while DKETS provide the hub to extend networked mission command to the tactical edge." Coile said.

 

Both SNAPs and DKETs were designed to have maximum interoperability within the Army and with Joint Forces and tie into the greater WIN-T network. SNAPs can link into Regional Hub Nodes, Unit Hub Nodes, and into DKETs, which provide much larger bandwidth capabilities and volume distribution.

 

"Having both the SNAPs and DKETs certified at Ka and X bands changes the communication landscape and augments the WIN-T architecture of the Tactical Hub Nodes, Satellite Transportable Terminals, unit hub SATCOM trucks and regional hubs," said Crudo.

 

As more SNAPs are fielded to augment the units, there is only so much capacity the unit hubs can bear, so having the SNAPs link into the DKET terminals is a viable alternative. DKETs also pass along other communication traffic that supplement the capability of the TAC Hub Nodes. In addition, within the WIN-T Increment 1 network, STTs link either into unit hub SATCOM trucks or into regional hubs. However, when needed, STTs can also link into DKET terminals.

 

Additional kits will be provided for existing SNAP terminals in theater that do not have the upgraded capability to enable them to receive the Ka an X band frequencies. The DKETs antenna is capable of receiving and transmitting Ku, Ka or X band; however, there is some equipment that needs to be changed in order to provide the desired band.

 

Because the DOD's high efficiency requirements, using Ka and X is more efficient and effective than Ku-band, and there are significant cost savings by not having to lease commercial satellite time.

 

"Since Ka or X band terminals are certified, the Army Signal Soldiers can utilize military satellites, and not pay any additional dollars to use the military satellites," Coile said. "They put in a request, it gets approved, and they do not have to pay for that transponder space."

 

In order for the government to utilize commercial satellites, it must pay for the bandwidth or transponder space. Therefore, the military must be efficient in their use of commercial satellite resources to reduce cost.

 

Use of military satellite resources significantly reduces cost, but the government is still very concerned about the bandwidth efficiency and how much of that satellite power is being utilized.

 

The amount of available space is limited and has to be prioritized, Coile said.

 

"It's a pie and there is only so much to divvy up for all of the requirements of each particular area of operation," Coile said.

 

Since these are DOD assets, the Army is required to put in a request for the allocation of a set amount of transponder space on the satellite. To obtain use on a military satellite, a Satellite Access Request is submitted by an organization up through its chain of command. Ultimately the Combatant Command is the controlling authority of the satellite resources in a specific area of responsibility, or AOR.

 

For example, in the case of Iraq and Afghanistan, CENTCOM has a satellite planning cell dedicated to oversee these resources. The DOD provides resources to CENTCOM, which would then distribute it within their AOR, Epperson said.

 

While the Air Force is responsible for developing and building the actual satellites, the Army has developed, procured and fielded the earth terminals such as SNAPs and DKETs. The Joint forces work together to ensure successful interoperability.

 

"The Ka and X band certifications for SNAPs and DKETs is an important step in decreasing the Army's reliability of commercial satellite use," Coile said. "It allows the military the flexibility of moving beams or allocating transponder space as different missions or new conflicts arise without having to deal with contractual issues with the commercial sector."

SBIRS Concept: Lockheed Martin

 

Sep 13, 2011 By Amy Butler -  aerospace daily and defense report

 

Though U.S. Air Force officials are hailing the forthcoming launch of a military payload hosted on a commercial satellite, funding could be an obstacle to a future Pentagon satellite infrastructure that relies heavily on hosted payloads for service.

 

SES-2 is slated to launch Sept. 17 on an Ariane 5 rocket. The satellite, made by Orbital Sciences Corp., will carry the Commercially Hosted Infrared Payload (Chirp) made by Science Applications International Corp. (SAIC).

 

The project is a “hallmark of cooperation and opportunity” that brought together an “incredible combination of different interests,” says Douglas Loverro, executive director of the Air Force Space and Missile Systems Center (SMC).

 

The payload includes one of four infrared telescopes designed by SAIC under an Air Force program started in the middle of the decade to find an alternative in the event that the performance of Space-Based Infrared System (Sbirs) prime contractor Lockheed Martin continued to disappoint, threatening to expose a gap in ballistic missile warning.

 

The government opted to use one of the 2,000 X 2,000-pixel wide-field-of-view staring infrared arrays for experimentation. The concept emerged through a proposal from SES, Orbital (the satellite manufacturer) and SAIC.

 

In total, the government spent about $216 million developing the sensors, readying the payload and integrating it onto the satellite, Loverro says. Originally, the sensor piece of the project was slated to cost $65 million. That changed to about $82.5 million owing to a one-year delay in the project, says Lt. Col. William McGuffey, director of SMC’s space projects division.

 

Tip Osterthaler, president and CEO of SES Government Solutions, says Chirp is expected to reach orbit at about 15% of the typical cost for a government payload to be lofted.

 

Loverro, however, notes that while qualified for space operations, the Chirp payload is not designed to meet the rigorous demands of nuclear hardening and integrated threat-warning and attack-assessment certification required for the Sbirs satellites.

 

However, with the cost of the first Sbirs and Advanced Extremely High-Frequency satellites at well more than $1 billion, Loverro says he is exploring constellations that provide an alternative to simply buying more of these large spacecraft. AEHF is designed to provide jam-proof communications, including traffic to nuclear forces in the event of a nuclear war.

 

Loverro suggests, for example, that alternative Sbirs and AEHF fleets could reserve the nuclear-hardened portions of the mission for the basic spacecraft, with hosted payloads providing augmenting data. Both of these missions require hardware in the geosynchronous belt, where many commercial spacecraft operate.

 

The question, however, is if this alternative approach will prove to be less costly. “If you can’t develop an architecture where the hosted payloads don’t decrease the cost of the rest of the architecture, then they really can’t earn their way onto the plate,” Loverro says.

 

He says he still has a year of work to do to refine these alternative architecture concepts.

 

In the meantime, Air Force officials will experiment with Chirp. Initially, the satellite will be inserted at 77 deg. West and eventually shift to 87 deg. West, its final operational slot. The Air Force plans to experiment with Chirp for just more than nine months. The orbital location is situated to provide coverage of infrared events on the West Coast of the U.S. as well as at White Sands Missile Range, N.M.

Europe Flag

 

13 Sep 2011By JULIAN HALE Defensenews

 

BRUSSELS - The European Union is stepping up its efforts to persuade other countries to sign an EU voluntary code of conduct on outer space activities, a senior official said Sept. 13 at an annual space conference hosted by the French think tank the Institut Francais des Relations Internationales and the Secure World Foundation.

 

The code aims to improve security in space for all nations, to prevent an arms race and to limit space debris.

 

On the same day, meeting in the EU's Political and Security Committee, national ambassadors for foreign affairs to the EU agreed to move from bilateral to multilateral consultations with non-EU countries. The idea is to hold a first multilateral experts' meeting in November or December.

 

The U.N. is conducting a similar exercise, the senior official said, but it "would start work in July 2012" and is expected "to take years to get to a text." He explained that the EU initiative was being taken outside the U.N. framework to "do something quick so that [the issue] is not blocked for several years."

 

An analyst at the conference indicated that space debris is a growing problem, while another stressed the importance of preventing an arms space race.

 

A draft of the EU code of conduct was adopted in October 2010 but "is not set in stone" and is "a living document" open to comments from partners, the official said. As it stands, signatories would agree to "resolve to promote further security guarantees within the appropriate fora for the purposes of enhancing the security of outer space activities by all states and the prevention of an arms race in outer space," and to "refrain from the intentional destruction of any on-orbit space object or other activities which may generate long-lived space debris."

 

The official said that the EU has had most detailed discussions with the U.S., which was "supporting the EU," while consultations with China in July had been "very difficult."

 

"China thinks that space debris shouldn't be one of the main objectives of the code," he said.

 

The code also provides for signatories to share information on their space policies and strategies, including basic objectives for security- and defense-related activities in outer space. For China, it would be "impossible" to give information on security and defense activities, the official said. Developing countries fear this is a Western initiative designed to block them from access to outer space, he said.

13-09-2011 - REF. : 20110913IPR26450 - europarl.europa.eu

 

Dès 2014, le système européen de navigation par satellite Galileo offrira un signal GPS réservé à des utilisateurs autorisés, tels que les services de police, l'armée et les services de sécurité, en plus des signaux destinés à la navigation en général. Le Parlement a approuvé une réglementation précise régissant le futur "service public réglementé" de Galileo, qui devrait être en place à la mi-octobre.

 

La réglementation définit les droits d'accès aux signaux cryptés, ainsi que les conditions de mise au point et de commercialisation, par les entreprises, des applications logicielles et des dispositifs de navigation. Le rapport a été adopté par 556 voix pour, 71 contre et 30 abstentions.

 

Galileo offrira cinq services distincts: le service ouvert, le service commercial, le service sécurisé, le service de recherche et de sauvetage et le service public réglementé (PRS). Le PRS, l'un des trois services qui pourraient être proposés à partir de 2014, sera exclusivement réservé aux utilisateurs autorisés par les gouvernements pour des applications sensibles telles qu'infrastructures critiques, trafic, défense, sécurité et services d'urgence.  Les applications nécessiteront une précision et une fiabilité de premier ordre, raison pour laquelle le PRS utilisera des signaux puissants et cryptés.

 

Le grand public n'aura pas accès au PRS qui sera réservé aux États membres et aux institutions de l'UE, alors que les agences de l'Union européenne, les pays tiers et les organisations internationales pourront l'utiliser sur autorisation spéciale.

 

Conditions d'utilisation

 

La réglementation fait une distinction claire entre les participants, tels que les États membres, le Conseil, la Commission (ainsi que les agences de l'UE, les États tiers et les organisations internationales) et les usagers du PRS, tels que les entreprises, autorités et personnes physiques autorisées par les participants à développer, à détenir ou à utiliser les récepteurs. Les usagers devront respecter des impératifs de sécurité et appliquer des clés de chiffrement lors de l'utilisation.

 

Chaque État membre décidera des utilisations qui seront faites du PRS, toutefois dans le respect des normes de sécurité minimum. Il désignera une Autorité PRS responsable pour la gestion et la supervision de tous les usagers autorisés. La fabrication des récepteurs nécessitera une autorisation européenne, alors que les exportations d'équipements et de technologie seront soumises à des prescriptions strictes.

 

Il appartiendra à chaque État membre de participer au PRS, d'en fixer les modalités d'utilisation et de décider d'en faire un service payant pour les usagers.

September 9th, 2011 By Forecast International, DEFENCE TALK

 

Forecast International projects that the worldwide military satellite market will be worth $42.5 billion, based on production of 180 military satellites, from 2011-2020.

 

Thirty-five satellite programs are covered in the company's "The Market for Military Satellites" study, which notes that these orbiting systems play a significant role in modern military operations, particularly in the U.S., which relies heavily on communications and reconnaissance to achieve its goals on the battlefield.

 

"With the increased focus on battlefield networking, communications satellite capacity is critical," said William Ostrove, aerospace systems analyst and author of the report. Satellites are also used for navigation and weather forecasting.

 

The analysis addresses some of the difficulties facing the market as a result of tight government budgets worldwide. "Governments are faced with large debt, and are reducing spending plans in response," said Ostrove. With respect to military satellites, budget cuts will be felt the most in the U.S., where satellite manufacturers have long enjoyed lucrative development and production contracts.

 

According to the study, the tougher budget environment is prompting the U.S. to focus on production of already-developed satellites, rather than on development of revolutionary new technology. The U.S. Department of Defense will also place more emphasis on smaller, inexpensive satellites under a concept known as Operationally Responsive Space (ORS).

 

Other concepts being pursued by military buyers include increased reliance on commercial satellite capacity, and greater purchases of hosted payloads. The study says that the U.S. has depended on commercial satellite operators for some time; however, as the demand for bandwidth increases, the military will increasingly rely on commercial satellite operators. Likewise, the military will rely more heavily on hosted payloads. Ostrove states that hosted payloads will become more commonplace as time goes by.

 

Despite budget troubles, the United States remains the most significant market in the world for military satellites. In terms of value, the United States will account for nearly three-quarters of military satellite production over the next 10 years, according to the report. Other notable military satellite purchasers during the period will include Japan, France, Russia, and China. U.S.-based companies Boeing and Lockheed Martin will benefit from the DoD's reliance on satellites, and they top Forecast International's list of prominent manufacturers during the 2011-2020 period. Mitsubishi, EADS Astrium, and ISS Reshetnev will also see significant production.

7 septembre 2011 par Edouard Maire – INFO-AVIATION

 

Le 2 septembre, Ball Aerospace Corporation a reçu un contrat de 36,9 millions de dollars pour entreprendre la phase 2 du programme MOIRE. Ce dernier doit permettre aux États-Unis d’assurer une surveillance en temps réel de toute la planète à l’aide de télescopes spatiaux munis de membranes optiques.

 

Le travail sera effectué à Broomfield et réparti selon les prestataires suivants : CO (73,2%); Livermore, CA (7,2%); Goleta, CA (17,2%) et Huntsville, AL (2,4%). Les travaux devront être achevés d’ici le 10 février 2013.

 

Amorcé en mars 2010 par le DARPA, le programme MOIRE (Membrane Optic Imager Real-Time Exploitation) répond aux besoins des États-Unis de s’assurer une imagerie intégrale de tout un territoire. Véritable « vidéo surveillance de la planète » le MOIRE permettra d’exploiter des images et des vidéos en temps réel depuis n’importe quel endroit sur ​Terre et à tout moment.

 

Ce système n’existe pas actuellement. Aujourd’hui, l’imagerie est opérée par certains avions comme le U-2, et des satellites dont le spectre ne permet pas de couvrir une zone suffisamment large. Cela oblige les USA à maintenir une quantité importantes de satellites pour un coût exorbitant (500 millions $ par satellite).

 

Un système MOIRE serait très utile pour repérer un drone intrus qui est susceptible d’être abattu, ou pour superviser la conduite des opérations militaires dans une vaste zone. L’armée américaine n’a d’ailleurs pas oublié l’immense difficulté qu’elle a éprouvé à localiser les batteries de missiles Scud pendant l’opération « Desert Storm » en 1991, malgré une maîtrise totale de l’espace aérien irakien.

 

Le programme MOIRE utilisera un système d’imagerie à couverture persistante en orbite terrestre géosynchrone (GEO), c’est à dire en étant synchronisé avec la rotation de la Terre, à une altitude d’environ 36.000 kilomètres. Pour cela, le MOIRE utilise une membrane optique légère sur laquelle est gravé un motif de diffraction. Ce motif est utilisé pour focaliser la lumière sur un capteur et la membrane est installée sur des plates-formes spatiales.

 

Le défi est grand car il s’agit de pouvoir fabriquer une membrane géante de 20 mètres de diamètre couvrant une superficie de plus de 10 × 10 km au moins une fois par seconde, avec une résolution au sol de 2,5 mètres, et la capacité à détecter les véhicules en mouvement. Au total, ce serait plus de 10 millions de kilomètres carrés qui pourraient être couverts par l’orbite géosynchrone du MOIRE.

 

Il s’agit aussi de pouvoir construire des grandes structures pour tenir l’optique à plat, et de monter les éléments optiques secondaires pour transformer une optique de diffraction basée sur un dispositif d’imagerie à large bande passante (transmission des images au sol).

 

Le programme MOIRE comprend ainsi plusieurs phases: phase 1 (étude du concept), phase 2 (conception du système) et phase 3 (démonstration du système). Le programme n’était jusqu’à présent qu’en phase 1 et des plans pour la transition à la phase 2 étaient prévus pour l’automne 2011. Le calendrier est donc bien respecté avec le contrat de Ball Aerospace.

 

Le 25 juillet 2011, le laboratoire national Lawrence Livermore (dédié à la science et aux applications des photons) a achevé la construction d’une première membrane optique de 80 cm de diamètre et 18 microns d’épaisseur de diffraction (photo), conçu en partenariat avec Ball Aerospace et Nexsolve Corp.

 

La membrane a été imprimée et gravée à une échelle de 4 microns, et sera testée dans les installations de Ball Aerospace pour les premières démonstrations.

 

Cette phase 2 va permettre de produire et tester un télescope de 5 mètres.

 

La phase 3 passera à la démonstration avec un télescope spatial de 10 mètres, en orbite géosynchrone, utilisant une membrane de diffraction optique. Il faudra alors programmer un lancement spatial (qui n’est pas bon marché) avec une charge utile secondaire de 5 mètres de carénage sur une fusée EELV-M de classe moyenne, et en utilisant une masse au lancement de moins d’une tonne.

Lockheed Martin has successfully completed thermal vacuum testing of the US Navy's first Mobile User Objective System (MUOS) satellite, a major program milestone that validates spacecraft performance in a simulated test-like-you-fly space environment.

 

A next-generation narrowband tactical satellite communications system, MUOS will provide significantly improved and assured communications for mobile warfighters. It will augment and ultimately replace the current UHF system and provide 10 times more communications capability to the user, including simultaneous voice, video and data.

 

Conducted inside Lockheed Martin's Dual Entry Large Thermal Altitude chamber, the MUOS spacecraft was stressed in a vacuum environment at the extreme hot and cold temperatures it will experience throughout its design life.

 

This major milestone was the culmination of an extensive test program that proves the spacecraft's overall design, quality of workmanship and survivability during space vehicle launching and on-orbit operation environments.

 

Thermal vacuum testing of the first MUOS satellite was completed later than originally planned as the team worked to validate the performance of this state-of-the-art spacecraft. While issues with specific legacy payload components were encountered during the test, Lockheed Martin was able to resolve each issue prior to completing thermal vacuum testing and entering final integration system testing in preparation for delivery.

 

"The team worked extremely hard to complete this important test phase in a disciplined and timely fashion to support our customer's launch needs," said Mark Pasquale, Lockheed Martin vice president and MUOS program manager. "The test confirms the spacecraft's ability to provide critical on-the-move communications for our deployed forces in remote and rugged locations and represents a pivotal moment toward achieving mission success on this program."

 

The first MUOS satellite, along with the associated ground system, is on track to support launch in the first quarter of 2012.

Lockheed Martin concept

 

Sep 6, 2011 By Amy Butler aerospace daily and defense report

 

Raytheon has completed the action items that emerged from the U.S. Air Force’s preliminary design review of the next-generation GPS control segment.

 

The four-day review took place at the end of June, and the final action items were completed in late August, says Bob Canty, vice president to the so-called GPS OSX effort. “The design itself was assessed as architecturally and technically sound,” he says.

 

Raytheon’s $886 million contract includes development as well as delivery of control segment hardware at Schriever AFB, Colo., and Vandenberg AFB, Calif., and updates to 17 monitoring stations around the globe. Canty says that with the new control system, the goal is to reduce the sustainment cost by 27% initially and within three years boost those savings to 50% of the existing system.

 

Block I, including hardware for Schriever and Vandenberg and the monitoring stations, is set for October 2015; the fielding of Block II, which will include the L2C signals, is scheduled for a year later.

 

The Block I system also will be able to operate with the new M-Code signals on the GPS satellites.

 

About 66% of the initial software is developed, though not all is tested, Canty says.

 

While Raytheon develops the new control segment, Lockheed Martin is designing the new GPS III satellites. The Air Force crafted a bifurcated procurement strategy, intentionally splitting the ground control segment contract from the satellite portion. This has, thus far, had the intended effect of preventing the ground system coffers being raided to pay for satellite work, Canty says.

Aug 18, 2011 by Scott Prater for 50th Space Wing - SPX

 

Schriever AFB CO (AFNS) - Members of the 3rd Space Operations Squadron, along with their counterparts from the 53rd Signal Battalion, waved a fond farewell to a trusted old friend Aug. 12. Lt. Col. Kevin Mortensen, 3rd SOPS commander and Lt. Col. Benjamin Jones, 53rd SB commander, took the honors, shutting down the final components of the satellite simply known as "B9," with a couple of mouse clicks.

 

And with that, a Defense Satellite Communications System vehicle that served both the U.S. Air Force and U.S. Army for 18 years sent its last bit of vital information.

 

"A lot of world events happened under the footprint of this satellite," said Lt. Col. Greg Karahalis, 3rd SOPS operations officer. "It's 18 years old and been in service on active duty longer than many of us. It's a Soldier and an Airman and that's how we like to talk about it. The events it has been through bare some recognition in terms of how it has performed and the contribution it's made to extending the life of the DSCS constellation."

 

Launched from Cape Canaveral Air Force Station aboard an Atlas II rocket July 19, 1993, DSCS B9 reached geosynchronous orbit on schedule and entered service following a two-month checkout.

 

While Air Force operations squadrons have controlled the space vehicle, its communications payload has been managed and operated by Army units. B9 served users as the West Pacific wideband satellite for most of its operational life.

 

According to Maj. Mike Reeder, 53 SB executive officer, B9 supported multiple missions, including the Diplomatic Telecommunications Service, the U.S. Navy's Surveillance

 

Towed Array Sensor System and the White House Communications Agency [presidential support]. It also supported U.S. military operations including Global Thunder and Terminal Fury and assisted in humanitarian efforts such as the Tsunami relief of 2004.

 

Spacecraft control authority for the entire DSCS constellation was transferred from the 5th Space Operations Squadron to 3 SOPS during 1996. Launched with a design life of 10 years, B9 easily blew through that envelope, serving for 13 years on orbit before telemetry data indicated that it was running low on fuel. Rather than give up and dispose of a fully functional satellite, the DSCS team refined and improved its fuel estimation capabilities and managed to squeeze an additional two and half year of life out of the spacecraft.

 

The DSCS team earned the 2006 Air Force Chief of Staff Team Excellence award for that specific effort on B9, but the old bird showed that it wasn't done just yet. During April 2008, B9 was placed in super synchronous orbit as a test asset.

 

"The best simulator on the ground is nowhere near as good as an actual satellite on orbit for realistic testing," Karahalis said. "The DCSC team has used B9 as a test asset for more than three years and we've made every effort to take full advantage of the unique opportunity."

 

As the spacecraft crept up in age, B9 was used in more than 15 end-of-life tests, which provided valuable information applicable to the entire DSCS constellation.

 

The spacecraft aided 3rd SOPS during anomaly investigations by allowing engineers to recreate abnormal conditions and helped extend the life of the constellation by enabling engineers to validate contingency procedures and mitigation strategies prior to implementation on operational vehicles.

 

"It has also provided a platform for running experimental procedures," Karahalis said. "This helps us push the operational envelope of the constellation and maximize spacecraft utility."

 

Capt. Kyle Volpe, 3rd SOPS' DSCS III engineering section chief, explained that B9's deactivation process was spread out over a two day period as crews first purged the vehicle of any remaining fuel and then began shutting off the payload and subsystem components on the subsequent day.

 

Even then, B9 refused to go quietly. Following a command to shutdown its reaction wheels, the satellite responded by deactivating only two of the four on board. It succumbed after the command was sent a second time, however, and few minutes later 3 SOPS and 53 SB members said their final farewells.

 

"DSCS B9's amazing mission accomplishment can be traced to the tremendous community that has supported it over the past 18 years," Mortensen said. "From Air Force and Army operators flying the satellite and payload, respectively, to our joint, acquisition, and industry partners working in close collaborations to ensure we provide National Command Authorities, Combatant Commanders, joint and allied forces, and other users around the world with reliable wideband satellite communications."

The SBIRS team is led by the Infrared Space Systems Directorate at the U.S. Air Force Space and Missile Systems Center. Lockheed Martin is the SBIRS prime contractor, with Northrop Grumman as the payload integrator. Air Force Space Command operates the SBIRS system.

 

Aug 17, 2011 Sunnyvale CA (SPX)

 

Lockheed Martin has successfully completed acoustic testing of the second Space Based Infrared System (SBIRS) geosynchronous (GEO-2) spacecraft.

 

The U.S. Air Force's SBIRS satellites provide the nation with significantly improved missile warning capabilities and simultaneously support other critical missions including missile defense, technical intelligence and battlespace awareness.

 

During acoustic testing, the fully integrated GEO-2 spacecraft was paced through the maximum sound and vibration levels expected during launch into orbit. Acoustic and pyroshock testing are among several critical environmental test phases that validate the overall satellite design, quality of workmanship and survivability during space vehicle launching and on-orbit operations.

 

GEO-2 will now undergo thermal vacuum testing, which will validate its performance at temperature extremes greater than those expected during on-orbit operations.

 

"SBIRS GEO-2 is progressing very smoothly on the path to delivery, and successful acoustic testing of the space vehicle is indicative of the team's increasing expertise in fielding SBIRS spacecraft," said Col Scott Larrimore, Chief of the U.S. Air Force's SBIRS Space Division.

 

"Our dedicated government and industry SBIRS team is focused on executing an efficient and thorough environmental test phase and ultimately delivering the much needed capabilities SBIRS GEO-2 will bring to our warfighter."

 

The first geosynchronous (GEO-1) SBIRS satellite was launched May 7, and has since reached orbit, deployed its instruments and activated its sophisticated infrared sensors.

 

GEO-1 is performing as expected, and is now undergoing early orbit testing. GEO-2 is on track to be delivered and available for launch in spring 2012.

 

"Leveraging expertise gained from GEO-1, our SBIRS team executed a very smooth acoustic testing phase on GEO-2," said Dave Sheridan, Lockheed Martin's SBIRS deputy program director.

 

"We understand the importance of the SBIRS system and are committed to delivering GEO-2 efficiently and affordably for our customer."

 

The SBIRS team is led by the Infrared Space Systems Directorate at the U.S. Air Force Space and Missile Systems Center. Lockheed Martin is the SBIRS prime contractor, with Northrop Grumman as the payload integrator. Air Force Space Command operates the SBIRS system.

 

Lockheed Martin's original SBIRS contract includes HEO payloads, two geosynchronous orbit (GEO) satellites, as well as ground-based assets to receive and process the infrared data.

 

The team is also under a follow-on production contract to deliver additional HEO payloads and the third and fourth GEO satellites, and associated ground modifications.

2011-07-25 (China Military News cited from smh.com.au and written by Dan Oakes)

 

CHINA'S satellite reconnaissance capabilities are rapidly approaching those of the United States and are increasingly geared towards military use, according to a US study.

 

The study by Eric Hagt and Matthew Durnin, obtained by the Herald, says a war in space between the US and China could be far more devastating than one fought on Earth.

 

''A war in space could be far more hazardous not least because the US military and economy are highly dependent on space,'' says the paper, which will appear in the Journal of Strategic Studies.

The paper says China is increasingly focusing on the military use of satellites. It says the US still has greater capacity to track moving targets, but that the Chinese have made huge strides in their ability to observe events as they unfold.

 

China's growing military strength is casting a lengthening shadow over the Asia Pacific region, prompting the US to guarantee its continuing presence in the region.

22 July, 2011, RT.com

 

Russia has completed the formation of its aerospace defense (VKO) – an analog of the European missile defense system - and it is expected to start operating on December 1, Lieut. Gen. Valery Ivanov, VKO commander, said on Friday.

 

July 22 is marked as the Day of Defenders in Moscow.On this day, 70 years ago, the Soviet air-defense troops repulsed the first massive air attack by Nazi bombers on the country's capital. Today, as memorial events were held to commemorate the heroes, Russia's modern air-defense was also in the spotlight.

 

Talking to journalists in the town of Mozhaisk in the Moscow region – where a monument to WW2 soldiers was erected – Valery Ivanov announced that "the aerospace defense system has already been created". It will enter service on December 1, cites Interfax. Currently, the VKO is “developing, improving, integrating, and modernizing”, the aerospace system commander noted.

 

"We are now merging our Space Forces with the operative strategic command of the aerospace defense system," he said.

 

In answer to a question regarding what the new entity would look like in the future – whether it would be a corps within a preexisting branch of the military or constitute a new branch of the Armed Forces of the Russian Federation, the commander said that that as of now, that point is yet to be determined.

 

“A final decision will be made by the political leadership of our state,” Ivanov said.

 

Earlier, in November 2010, President Dmitry Medvedev ordered that a united air and space defense system be created by 2011, one which would bring together the air defense and missile defense systems, as well as the early missile warning and space control systems, under a unified command.

 

Speaking on Friday, the VKO commander also said that by 2015, the Russian Army will get the S-500 Samoderzhets (Autocrat) surface-to-air missile system – a new generation of defense weaponry that is currently under development by the Almaz-Antey company.

 

"We will receive new radio technical equipment, new fighter jets, and new S-500 systems by 2015. These fifth-generation tools will form a shield over Moscow," Ivanov said. The system, which has a range of 600 km, will be able to simultaneously track and destroy up to 10 ballistic missiles at a range of 3,500 kilometers.

 

According to the military chief, the aerospace defense currently covers 2/3 of the territory of the Russian Federation with its shield.Every day, around 800 people are on duty to ensure Moscow's security, he added. The VKO's key task is to protect the capital and the central industrial regions.

21 July 2011 by defenceWeb Reuters

 

The United States wants to open a regular dialogue with China on outer space in an effort to create "rules for the road" and reduce the risk of misunderstandings, a U.S. defence official said on Tuesday.

 

China is making major investments in space and, unlike in the United States, distinguishing between China's civil and military space sectors is difficult because "the two are essentially one," Gregory Schulte, deputy assistant secretary of defence for space policy, said.

 

The United States recognizes that China is a "major space-faring country," he said.

 

China is developing a broader range of space-borne capabilities to ward off adversaries, including jammers and lasers, which provides added incentive for the United States to open a channel for talks.

 

"We've actually proposed to establish a regular dialogue with China on space," Schulte said.

 

"We're waiting to pick the date for the first discussion, but we're ready to go in to talk about this strategy, to talk about what we think responsible use of space looks like," he told a defence writers group. "To talk about ways to create rules for the road, and to talk about ways to reduce the risk of mishap or miscalculation or misunderstandings."

 

The U.S. offer of talks on space is similar to other proposals Washington has made, with mixed results, to increase China's transparency and ease Sino-American flashpoints, such as maritime operations in the Pacific.

 

Both the United States and China have a history of concerns about the other's operations in space.

 

In 2008 the U.S. military shot down a disabled U.S. spy satellite with a missile, saying it posed a danger to populated areas. Russia and China both expressed concerns.

 

That incident came a year after China shattered one of its aging weather satellites with a ground-based missile, which drew international criticism and prompted Pentagon worries that China had the ability to target military assets in space.

 

China is increasingly reliant on space for its military and economy, Schulte said. China has an interest in the responsible use of space and "in making sure that space doesn't somehow become a flashpoint in a future crisis," he said.

 

The defence official said the 2007 Chinese test of its anti-satellite system created about 14 percent of the debris that U.S. Strategic Command is currently tracking in outer space.

 

"STRATCOM is tracking over 22,000 objects, and that's only the ones that we can see," Schulte said.

 

U.S. Strategic Command in Nebraska delivers warnings of potential satellite collisions around the world. It has agreements with over 20 commercial owner/operators of satellites worldwide.

 

"We are getting ready to give it authority to negotiate agreements with foreign countries to share that same information," Schulte said.

 

Over the last year STRATCOM provided about 2,000 warnings of potential collisions to multiple countries, Schulte said. That included almost 150 warnings to China -- "and a lot of those warnings were for potential conjunctions (collisions) between a Chinese satellite and debris from the weather satellite that they shot in 2007," he said.

 

By giving STRATCOM authority to negotiate with foreign countries, the goal was to develop relationships and obtain information from those countries about scheduled maneuvers and positioning of their satellites, Schulte said.

CANNES, France, July 20 (UPI)

 

Thales Alenia Space Italia will study the definition and feasibility of Europe's Multinational Space-based Imaging System

 

The contract for the MUSIS Federated Activities program was signed with OCCAR-EA, the Organization for Joint Armament Cooperation, which was acting on behalf of the French and Italian ministries of defense and which awarded the contract to a temporary grouping of companies made up of Astrium of France and Thales Alenia Space France, led by Thales Alenia Space Italia.

 

The study is aimed at defining a common interoperability layer between the ground segments of the Italian COSMO-SkyMed Second Generation and the French CSO (Optical Space Component) high-resolution optical system.

 

The two defense ministries will be guaranteed access to both systems through this common interoperability, providing them with multi-sensor observation capabilities.

 

This approach has several objectives, including:

 

-- Guaranteed mutual access for Italy and France to both SAR and high- and very-high resolution optical satellite capabilities, at the same time ensuring suitable mutual confidentiality requirements.

 

-- Reduced life-cycle costs through the development of common user interfaces providing access for both national systems.

 

-- Ensured full consistency and compatibility with the development plans of the respective national programs.

 

The development of the common interoperability layer is part of the broader MUSIS program, which calls for a federation of several national systems endowed with complementary observation capabilities.

 

Italy will contribute to the program by building -- under the responsibility of the Italian Space Agency and the Ministry of Defense -- two satellites equipped with radar sensors, with active SAR antenna, called COSMO-SkyMed Second Generation.

 

Although primarily designed to meet Italy's and France's programs and operational needs, the development of CIL will also give other countries interested in the MUSIS program access to the CSG and CSO systems and possibly extend its functions to other federated space components.

 

With the start of the MUSIS-CIL project, France and Italy will further strengthen their profitable bilateral relationship, putting it in an even European broader context where they can achieve their respective objectives and attain a common goal.

 

Thales said the COSMO-SkyMed second-generation system represents the technological evolution of COSMO-SkyMed, made up of four satellites. The system "watches" the Earth day and night and under any atmospheric condition through the use of high-resolution X-band radar systems.

 

Thales Alenia Space is the prime contractor, with responsibility for the entire system, including the space and ground segment.

 

COSMO-SkyMed is managed by the Italian Space Agency within the scope of an ASI/Defense joint Program Office and is the first completely dual project developed worldwide.

 

The CSO is the follow-on to the Helios 2 French program for which Thales Alenia Space will supply the very-high-resolution optical imaging instrument.

 

The European leader in satellite systems and a major player in orbital infrastructures, Thales Alenia Space is a joint venture between Thales and Finmeccanica.

SBIRS GEO-1 Satellite to Provide a Quantum Leap in Infrared Surveillance Capabilities

 

The first Lockheed Martin built Space Based Infrared System (SBIRS) geosynchronous (GEO-1) spacecraft beamed down its first infrared image on June 21 to the SBIRS ground station. Following its May 7 launch, the satellite is performing as expected, and is now undergoing early orbit testing.

 

The U.S. Air Force’s SBIRS GEO-1 spacecraft is the most technologically advanced military infrared satellite ever developed. The system will enhance the military’s ability to detect missile launches around the globe, support the nation's ballistic missile defense system, greatly expand technical intelligence gathering capability, and bolster situational awareness for warfighters on the battlefield.

 

The satellite includes highly sophisticated scanning and staring sensors that deliver improved infrared sensitivity and a reduction in area revisit times over the current constellation. The scanning sensor will provide a wide area surveillance of missile launches and natural phenomena across the earth, while the staring sensor will be used to observe smaller areas of interest with superior sensitivity.

 

“We are tremendously proud of Team SBIRS for their superb efforts to initialize the Air Force’s newest, most capable infrared payload,” said Col. Mike Noble, Deputy Director of the U.S. Air Force Space and Missile Systems Center’s Infrared Space Systems Directorate. “This is another important milestone for the SBIRS’ Air Force and industry team. Successful payload activation is a major step toward fielding the all-new GEO capabilities for the nation and joint warfighters.”

 

After launch, the U.S. Air Force/Lockheed Martin SBIRS ground team executed a series of six Liquid Apogee Engine (LAE) burns to propel the spacecraft to its geosynchronous orbital slot. The team then deployed the satellite's solar arrays, light shade and antenna wing assemblies. Most recently, the team opened the satellite’s payload doors and activated its sophisticated infrared sensors to begin the start of early orbit calibration and testing.

 

“SBIRS GEO-1 is performing flawlessly thus far, and the first image sent from the satellite is outstanding,” said Jeff Smith, vice president of Lockheed Martin’s Overhead Persistent Infrared (OPIR) mission area. “We are focused on executing an efficient and thorough checkout of the spacecraft and ultimately delivering unprecedented infrared surveillance capabilities to our nation.”

 

The SBIRS team is led by the Infrared Space Systems Directorate at the U.S. Air Force Space and Missile Systems Center. Lockheed Martin is the SBIRS prime contractor, with Northrop Grumman as the payload integrator. Air Force Space Command operates the SBIRS system.

 

Lockheed Martin's original SBIRS contract includes HEO payloads, two geosynchronous orbit (GEO) satellites, as well as ground-based assets to receive and process the infrared data. The team is also under a follow-on production contract to deliver additional HEO payloads and the third and fourth GEO satellites, and associated ground modifications.

 

Headquartered in Bethesda, Md., Lockheed Martin is a global security company that employs about 126,000 people worldwide and is principally engaged in the research, design, development, manufacture, integration and sustainment of advanced technology systems, products and services. The Corporation's 2010 sales from continuing operations were $45.8 billion.

The SBIRS team is led by the Infrared Space Systems Directorate at the U.S. Air Force Space and Missile Systems Center. Lockheed Martin is the SBIRS prime contractor, with Northrop Grumman as the payload integrator. Air Force Space Command operates the SBIRS system.

 

Lockheed Martin's original SBIRS contract includes HEO payloads, two geosynchronous orbit (GEO) satellites, as well as ground-based assets to receive and process the infrared data. The team is also under a follow-on production contract to deliver additional HEO payloads and the third and fourth GEO satellites, and associated ground modifications.

Le ministère de la Défense doit "renoncer" à l’opération Nectar qui consiste à céder à un opérateur privé l’usufruit des satellites de télécommunications militaires Syracuse, avancent les députés Louis Giscard d’Estaing (UMP)et Bernard Cazeneuve (PS), auteurs d’un rapport de la mission d’évaluation et de contrôle sur les externalisations dans le domaine de la défense.

 

Cette opération de cession-bail "s’apparente davantage à une opération de trésorerie destinée à engranger une recette exceptionnelle, qu’à un réel partenariat public-privé", soulignent les deux députés, qui ajoutent que "la Direction générale de l’armement (DGA), elle-même n’est pas sûre que (…) l’opération sera rentable".

Dans un "bilan des externalisations au ministère de la défense", début 2011, la Cour des comptes a fait le même constat, estimant, elle aussi, que l'opération Nectar "obéit plus à la volonté de créer des recettes exceptionnelles qu’à une opération d’externalisation".

 

Le projet prévoit que l’armée cède à titre onéreux les deux satellites Syracuse actuellement en orbite à un opérateur privé, ce dernier s'engageant à gérer les communications satellitaires du ministère de la Défense, moyennant un loyer qui lui sera versé. Les capacités non utilisées par les armées pourront être proposées à d’autres clients. la défense attend quelque 400 millions d'euros de cette cession.

 

Retard


La rentabilité globale du projet "est en cause en raison du retard pris par cette opération, évoquée depuis 2008 mais sans cesse retardée", indiquent MM. Giscard d’Estaing et Cazeneuve, qui indiquant que "la durée de fonctionnement résiduelle des satellites Syracuse est limitée à 2017 ou 2018".

 

"Tout retard dans la signature du contrat entraîne mécaniquement une réduction du prix d’acquisition qui sera proposé par les opérateurs", notent les deux députés, ajoutant que la DGA "n’est pas sûre que la somme proposée par les candidats soit supérieure aux loyers à payer".

 

Au-delà de l'aspect financier, les deux élus pointent aussi "les dangers induits par une perte de compétence dans un domaine aussi essentiel pour le caractère opérationnel des armées".

Terma’s BMD-Flex has participated in a successful “live fire” test by the U.S. Missile Defence Agency (MDA) from the U.S. Navy’s Space and Air Warfare Systems Center (SSC) collocated with headquarters of the U.S. third fleet in San Diego.

 

During the test, BMD-Flex received the track of the intermediate range ballistic missile as well as the launch point and impact point.

 

This demonstrates the capability of the first phase of the phased, adaptive approach for missile defense in Europe which was announced by President Obama in September 2009. In relation to BMD-Flex, the test proves how Terma’s solution is fully interoperable with the assets which will be deployed in Europe as of 2011 and scheduled to be complete in 2020.

 

BMD-Flex is an international command and control system for integrated air and missile defense. Its flexible design makes it the perfect choice for both land-based and sea-based defense of deployed forces as well as population centers against the growing threat from ballistic missiles throughout the world.

 

Collaboration between Lockheed Martin (LMMS2) and Terma has resulted in an integrated air and missile defense which is agile, modular, scalable, and tailorable to the needs of the customer. The approach is based on an open architecture allowing an initial capability for the integration of air and/or missile defense.

 

The MDA, U.S. Navy sailors aboard the Aegis destroyer USS O’KANE, and soldiers from the 94th Army Air and Missile Defense Command operating from the 613th Air and Space Operations Center at Hickam Air Force Base, Hawaii, successfully conducted a flight test of the Aegis Ballistic Missile Defense (BMD) element of the U.S. Ballistic Missile Defense System, resulting in the intercept of a separating ballistic missile target over the Pacific Ocean. It was the culmination of a series of successful tests, including lab tests with simulated and recorded live data as well as participation in multiple NATO Coalition Warrior Interoperability Demonstrations.

July 7th, 2011 By Lockheed Martin DEFENCE TALK,

 

Lockheed Martin has announced that the Multi-Mission Satellite Operations Center Ground System Architecture recently extended its mission capability to Schriever Air Force Base, Colo., with the successful launch of a new Air Force Operationally Responsive Space mission satellite, ORS-1.

 

The ORS mission will be deployed by the 1st Space Operations Squadron, a component of the 50th Space Wing at Schriever.

 

The architecture was developed by Lockheed Martin and the Air Force's Space and Missile Systems Center Space Development and Test Directorate to allow the Air Force to operate different types of satellites with the same ground system.

 

"We need to drive cost down and operational agility up. In an era where we're flying a lot of unique missions, the ability to fly a lot of satellites with the same ground architecture is critical," said U.S. Air Force Col. Michael Moran, commander of the Air Force Space Development and Test Wing, in a recent interview with Space News.

 

"By building a single ground architecture, we can very rapidly transition research and development capabilities to the operational world."

 

In support of the ORS-1 mission, Lockheed Martin extended the MMSOC architecture to interface with the ORS-1 tasking system. This direct tasking will decrease the turnaround time of the ORS-1 products to military commanders.

 

"Lockheed Martin is proud to be a part of this exciting transition to more affordable and responsive space operations," said Bob Kramer, Lockheed Martin Information Systems and Global Services-Defense's vice president for Operational Systems and Solutions.

 

"This new MMSOC interface allows military commanders to task the spacecraft payload through the MMSOC ground system."

 

This is the second satellite being supported by MMSOC, which has been flying a Space Test Program Satellite, STPSat-2, at Kirtland Air Force Base, N.M., since its launch in November.

 

Using Lockheed Martin's HORIZON satellite command and control framework, MMSOC ground system architecture consolidates satellite operations by providing an over-arching ground segment architecture for one-of-a-kind technology demonstrations and responsive space operations.

 

The Space Development and Test Directorate develops, tests and evaluates Air Force space systems, executes advanced space development and demonstration projects, and rapidly transitions capabilities to the war fighter. Located at Kirtland AFB, the Directorate is responsible for providing mission support to the operationally responsive space community.

The service guarantees maximum availability of the equipment and helps reduce maintenance-related costs

 

July 5, 2011 defpro.com

 

Indra signed a framework agreement with the Ministry of Defence for the maintenance of the satellite terminals of the Spanish Satellite Military Communications System (SECOMSAT). The agreement, for €17 million, awards the provision of these services exclusively to the premier IT company in Spain and a leading IT multinational in Europe, for the next two years extendable to two more years.

 

This maintenance and life cycle engineering service will be commissioned by the final users, that is, the different branches of the army and other organs. The service will be customised to meet their needs and will comply with the requirements established in the contract.

 

The satellite communications systems are employed by organs of the Ministry of Interior, the three branches of the army and the Military Emergency Unit. Thanks to the exclusive provision of the services costs can be reduced by means of synergies, scale economy and availability of the equipment relies on a single provider.

 

Maintenance will have a preventive (detection of possible failures in order to anticipate a response) and a corrective character. On the other hand, the engineering works are oriented to extend their service life.

 

Indra undertook the development of the stations, the management system of the Secomsat network and of the communication terminals included in this contract.

 

The company has delivered and integrated terminals for surface ships and submarines, tactical, multi band, and man-pack type terminals, which can be carried by a single person. It has also delivered several types of terminals to be embarked on top of vehicles, which guarantee satellite communications among the terminals of deployed troops and with the command and control centre of the Unit.

 

Secure communications networks provide connection between troops, either in international or national missions, with the Command and control. They have been designed to guarantee performance as they do not depend on third parties infrastructures which may be incidentally affected.
