Chennai, India - The launch of the Radar Imaging Satellite (Risat-1) is a major step forward for India but it must increase its capacity and launch many more satellites to be considered a serious player in making military satellites, says an official of a US-based space consultancy firm.

 

"Risat-1 represents another step forward for India. Its synthetic aperture radar (SAR), which enables imaging through bad weather conditions during both day and night, will assist Indian land management, agriculture monitoring and resource observation. The satellite mission is in keeping with India's traditional use of space assets for social benefit," David Vaccaro, programme manager at the Futron Corporation, told IANS in an e-mail interview.

 

He, however, said India cannot be considered a major force in building military satellites at present.

 

"With the development of SAR imagers and applications, India is increasingly capable of producing satellites that could be used for surveillance and military reconnaissance. However, for it to become a greater player in this regard, it must first increase its capacity to build and launch such satellites quickly, and in larger volumes," Vaccaro said.

 

The Indian Space Research Organisation (ISRO) launched the 1,858 kg indigenously built Risat-1 from Sriharikota in Andhra Pradesh on its polar satellite launch vehicle (PSLV) April 26.

 

Vaccaro said, "India has moderately strong satellite manufacturing capabilities, but could benefit from greater privatisation and a deeper commercial focus."

 

Currently, the centralisation of satellite production in ISRO and Antrix Corporation (ISRO's commercial arm) is impeding the emergence of commercial satellite manufacturing firms, he remarked.

 

According to him, India has an advantage in its highly skilled human capital base.

 

Asked to compare between India and China in the space sector, Vaccaro said, "India's space strengths include its satellite programmes and applications, including meteorology, remote sensing, environmental imaging and telecommunications."

 

"By contrast, the most formidable Chinese space strengths are in its significant launch capacity and its human spaceflight programme. China performed more orbital launches in 2011 than the United States, a key milestone that placed China second only to Russia for the first time in history. China is also now one of only three countries to demonstrate human spaceflight capability, the others being Russia and the US," he added.

 

According to him, with effort, India is capable of joining the human space flight club. But this would entail a succession of tests leading up to an eventual manned launch.

 

"Unless the programme received the highest priority from the Indian government, it would require at least a decade for India to create its own indigenous human spaceflight capability," Vaccaro said.

 

India should invest in the infrastructure to perform more frequent orbital launch missions with consistent reliability, he suggested.

 

"With this infrastructure and track record in place, India will be able to play a larger role in more advanced missions, such as Moon or Mars efforts. And a more frequent launch tempo would also make India more of a player in the commercial launch market," he remarked.

May 9, 2012 (Released May 5, 2012) defpro.com

 

The Netherlands Defence organisation is now a step closer to satellite communications independence after the launch of a satellite from Cape Canaveral on 5 May. Prior to the launch, the Defence organisation was dependent on commercial parties in this area. The future capability will provide the most robust and secure link for communication of vital information.

 

The launch in Florida was the second in a series of four. The positioning of this second satellite makes it of vital importance to the Netherlands and its partner, the United Kingdom. The launch of a third satellite is planned for autumn 2013, while the launch date of the fourth has yet to be determined. The four satellites are launched, managed and controlled from the United States.

 

 

GUARANTEED

 

The launches are part of the Military Satellite Communications project, which involves funding amounting to €135.9 million. The objective of the project is to acquire guaranteed satellite capability for military use and involves satellite capability at various frequency bands, i.e. military Super High Frequency (SHF), commercial SHF and military Advanced Extreme High Frequency (AEHF). The United States, the United Kingdom, Canada and the Netherlands have formed a cooperative for the AEHF part of the project.

 

WORLDWIDE

 

The four aforementioned satellites carry AEHF capabilities and represent the final phase of the project. These AEHF satellites provide worldwide coverage. The Netherlands will mainly make use of the second satellite, positioned over the Equator and providing coverage of Europe, the Middle East and the Atlantic Ocean.

 

SHIP TERMINALS

 

In addition to the launch of the four satellites, permanent ground stations have been built in the Netherlands and on Curaçao and, moreover, mobile land and ship terminals have been purchased. AEHF capability is expected to become available to the Netherlands in 2013. The land terminals will be delivered in early 2013. For the Netherlands, the project will be rounded off by installation of the ship terminals on the four Royal Netherlands Navy air defence and command frigates. This will take place during the maintenance breaks planned in 2016.

3 May 2012 aerospace-technology.com

 

Lockheed Martin has successfully completed the integration of the spacecraft bus and imaging payload for GeoEye's next-generation, high-resolution imaging satellite, the GeoEye-2.

 

Lockheed Martin space systems GeoEye-2 programme director Allen Anderson said the key milestone paves the way for the team to begin system level environmental and acceptance testing in preparation for on-orbit operations in 2013.

 

"We are on track to complete the remaining integration and test work on-schedule and look forward to the ultimate deployment of this cutting-edge satellite," Anderson added.

 

Developed under a fixed-price contract by Lockheed Martin Space Systems, GeoEye-2 is being designed to provide high-resolution and accurate imagery to intelligence analysts, war fighters and decisions makers worldwide.

 

The GeoEye-2 bus, which is the structural foundation of the satellite, includes an integrated propulsion system and other critical subsystems for communications, attitude control, thermal control, command and data handling.

 

Equipped with a new ITT Exelis imaging system, the GeoEye-2 satellite will feature enhanced tasking capabilities, superior image quality and increased collection of imagery at a faster rate.

 

The imaging payload for the satellite consists of a telescope, sensor subsystem and outer barrel assembly, which enable 360° capturing of ground sample distance imagery of the Earth's surface from an altitude of 681km.

 

Commenting on the capabilities of the satellite, GeoEye's vice president of Engineering Carl Alleyne said: "GeoEye-2, with 0.34m resolution, will fully support all mission requirements and meet the US Government's exacting standards when operational in 2013."

 

The satellite will be launched aboard an Atlas V rocket by Lockheed Martin Commercial Launch Services.

India developing anti-satellite weapons

 

Apr 23, 2012 Spacewar.com (UPI)

 

New Delhi - India intends to develop anti-satellite weapons following its successful Agni-V ICBM test.

 

Indian Defense Research and Development Organization Director General and scientific adviser to the Defense Minister V. K. Saraswat said the launch of Agni-V last week opens a "new era" for India

 

"Apart from adding a new dimension to our strategic defense, it has ushered in fantastic opportunities in building ASAT weapons and launching mini/micro satellites on demand," he said.

 

ASAT weapons require reaching about 500 miles above the Earth. Saraswat said Agni-V delivers the boosting capability and the kill vehicle, "with advanced seekers, will be able to home into the target satellite."

 

Saraswat noted that Agni-V's range of more than 3,100 miles was sufficient to take care of India's current threat perceptions.

 

"We have no problem in augmenting the range if in the future, threat perceptions change," he said. "We are not in a missile race with anyone. We are building missiles to mitigate our threats."

 

Saraswat added that the government had yet to give formal approval to the ASAT program.

 

"India does not believe in weaponization of space," he said. "We are only talking about having the capability. There are no plans for offensive space capabilities."

 

Underpinning India's interest in an ASAT program was China's 2007 use of an ASAT weapon to destroy an old satellite.

 

In late 1962 India and China fought a brief war over contested Himalayan territory, during which India lost 1,383 killed, 1,047 wounded, 1,696 missing and 3,968 captured. Chinese losses during the conflict were 722 killed and 1,697 wounded.

 

In January 2010, Saraswat said: "India is putting together building blocks of technology that could be used to neutralize enemy satellites. We are working to ensure space security and protect our satellites. At the same time we are also working on how to deny the enemy access to its space assets."

 

The ABM elements in India's space program were operational tested last year. India performed a test in March 2010, the sixth of the series, of the interceptor missile portion of its ballistic missile defense system. The test was reported to be a success and a validation of the technology to be integrated into India's missile defense capabilities.

 

A modified Prithvi target missile, modified to mimic the trajectory of a ballistic missile with a 324-mile range, was launched from Chandipur, Orissa Integrated Test Range Launch Complex III.

 

Indian military radar tracked the launch, determined its trajectory and relayed the data in real time to Mission Control Center, which launched the interceptor. The interceptor's directional warhead was maneuvered into close proximity to the modified Prithvi before detonating, the government said.

Ariane-5-source-Arianespace.jpg

 

Apr 24, 2012 ASDNews Source : Arianespace

 

The Ariane 5 for Arianespace’s third heavy-lift mission of 2012 is now taking shape at the Spaceport, using procedures that have become routine with this workhorse vehicle’s operations from French Guiana.

 

During activity inside the Spaceport’s Launcher Integration Building, the core cryogenic stage was removed from its protective shipping container and raised into position over one of two operational mobile launch tables available for Ariane 5.

 

The pair of solid propellant boosters was then anchored to the launch table on each side of the core stage this weekend, readying them for mating to complete the vehicle’s initial assembly step.

 

This Ariane 5 will be used on a flight scheduled for June 19 with Europe’s Meteosat Second Generation-3 (MSG-3) weather satellite for the European Space Agency and EUMETSAT (the European Organisation for the Exploitation of Meteorological Satellites); along with  the EchoStar XVII high-throughput telecommunications platform for Hughes Network Systems.

new-gen-glonass-k-gps-lg.jpg

 

Russia is planning to spend $694 million on its Glonass system in 2012. The Kommersant daily has quoted government sources as saying that the project may cost the country 346.5 billion rubles (almost $12 bln) in 2012-2020.

 

Apr 19, 2012 (RIA Novosti)

 

Moscow -  Russia plans to begin testing its second Glonass-K navigation satellite in 2013, Grigory Stupak, the deputy head of the Russian Space Systems company producing navigation and other equipment for the satellite, said on Tuesday.

 

It was earlier reported that the satellite would be first tested by the end of 2012.

 

The first Glonass-K satellite was successfully tested in February 2011.

 

Glonass is Russia's answer to the U.S. Global Positioning System, or GPS, and is designed for both military and civilian uses. Both systems allow users to determine their positions to within a few meters.

 

Russia currently has a total of 31 Glonass satellites in orbit, with 24 operating to provide global coverage, four in reserve, two under maintenance and one undergoing trials.

 

According to Roscosmos, two Glonass satellites are under maintenance, one is on standby, and one recently launched satellite is being integrated into the grouping.

 

The complete Glonass grouping needs 24 functioning and 2-3 reserve satellites to operate with global coverage.

 

Russia is planning to spend $694 million on its Glonass system in 2012. The Kommersant daily has quoted government sources as saying that the project may cost the country 346.5 billion rubles (almost $12 bln) in 2012-2020.

 

In 2020, Russia plans to have 30 satellites in orbit, including six in reserve. To support the orbital grouping, Russia plans to launch 13 Glonass-M satellites in 2012-2020 and 22 new-generation Glonass-Ks to replace the outdated ones. Russia will build eight Proton-M and 11 Soyuz-2.1b carrier rockets for this purpose.

The Pentagon US Department of Defense building

 

Apr 17, 2012 By Andrea Shalal-Esa/Reuters AviationWeek.com

 

COLORADO SPRINGS, Colo. - The Obama administration will soon send Congress a long-awaited final report on loosening export controls on some satellites and associated equipment, a move that U.S. industry officials say could help them compete overseas while domestic spending falls.

 

Madelyn Creedon, assistant secretary of defense for global strategic affairs, told reporters at a space conference that she expected top U.S. defense officials to sign off on a report that explains the benefits and risks of loosening restrictions on some satellite components.

 

“We’ve been working on this for a long time,” Creedon said after a speech to the annual Space Foundation conference on Monday, adding that she expected an announcement in the near future, without giving an exact timetable.

 

Two sources familiar with the process but not authorized to speak publicly said the final report could be delivered to Congress as early as this week.

 

Industry officials said the report could pave the way for an easing of export controls on U.S.-built satellite products imposed by Congress in the late 1990s, when two U.S. companies were found to have provided unlicensed technical assistance to China’s space launch industry.

 

Creedon said the study included the same concepts but went into greater detail than a May 2011 draft which said that easing restrictions on some communications satellites would not pose an unacceptable security risk.

 

“It would make many companies more competitive internationally and ease business transactions for a whole range of commercial satellite activities,” said Patricia Cooper, president of the Satellite Industry Association.

 

Reforms of the tight current controls would give American firms a boost, said Craig Cooning, vice president and general manager of Boeing Space and Intelligence Systems. “It would let us compete against the French,” he said.

 

Congress would need to pass legislation to allow the administration to change the way satellite exports have been regulated since 1999, Creedon said.

 

One bill has already been introduced in the House of Representatives, and a similar measure is expected to be introduced in the Senate later this month.

 

U.S. satellite industry executives and their suppliers have long complained that the changes enacted in the late 1990s shut them out of international competitions.

 

U.S. market share of satellite exports has dropped from 75 percent in 1995 to just over 40 percent since the tough rules took effect over a decade ago.

Wideband-Global-SATCOM--WGS-.jpg

 

EL SEGUNDO, Calif., April 12, 2012 – Boeing

 

Boeing announced today that the U.S. Air Force accepted control of the fourth Wideband Global SATCOM (WGS) military communications satellite on April 11, after the spacecraft passed several weeks of rigorous on-orbit tests.

 

WGS-4 was launched Jan. 19 from Cape Canaveral Air Force Station, Fla., aboard a United Launch Alliance Delta IV rocket. It is the first spacecraft in the program's upgraded Block II series, which includes a new radio frequency (RF) bypass that supports the transmission of airborne intelligence, surveillance and reconnaissance imagery at data rates approximately three times greater than those currently available on Block I satellites.

 

"This fourth WGS satellite adds substantial capacity and resiliency to the WGS constellation," said Craig Cooning, vice president and general manager, Boeing Space & Intelligence Systems. "The team worked around the clock to ensure that all testing was completed successfully, and that the satellite was healthy and ready for customer handover. We remain committed to the Air Force, the WGS mission, and to continuing to support the delivery of this critical enhancement of warfighter communications."

 

On-orbit testing demonstrated the functionality of WGS-4's communications payload features by passing test signals through each of the satellite's 19 antenna beams. The tests also verified WGS-4's beam-steering functions.

 

Boeing performed the on-orbit testing from the company's Mission Control Center in El Segundo and from government facilities in central California. Air Force operations personnel at Schriever Air Force Base in Colorado are conducting additional tests and preparing to move WGS-4 into its operational position. The satellite is expected to go into service this summer.

 

WGS satellites are built on the proven Boeing 702HP platform, which features highly efficient xenon-ion propulsion, deployable thermal radiators, and advanced triple-junction gallium-arsenide solar arrays that enable high-capacity, flexible payloads. The WGS communications payload has unique flexibility that is important to the military, as well as the ability to interconnect terminals that operate in different frequency bands and to reposition coverage beams based on evolving mission needs. WGS supports missions including tactical communications to and between ground forces, and relaying data and imagery from airborne intelligence, surveillance and reconnaissance platforms.

12.04.2012 DEFENSE STUDIES

 

A NEW SATELLITE was successfully launched in Kazakhstan last week, which will improve communications abilities for Australian Defence Force personnel operating in the Middle East.

The IS-22 satellite was launched from Baikonur Cosmodrome in Kazakhstan. The launch was managed by Intelsat, an international satellite service provider.

 

 


The Australian Defence Force has purchased an Ultra High Frequency communications payload, which forms part of the satellite. More than 30 per cent of the satellite is dedicated to Australian Defence communications.


“This satellite means we will be able to transmit voice and data anywhere between the west coast of Africa and the east coast of Australia,” said Minister for Defence Materiel Jason Clare. “It will make it easier for commanders in Australia to provide troops on the ground with information faster and more effectively.

 


“It will also mean that troops can provide intelligence and information back to Headquarters.”
Currently, the ADF has limited use of United States’ satellites in this region.

 

The launch of the IS-22 means that Australia now has its own dedicated Defence satellite communications network in this region.

 


The satellite will also be used for commercial purposes, but Defence has put in place high level security measures including data encryption to protect ADF communication links.

 

The $269 million program has delivered the project on time and within budget. Intelsat is contracted to operate the satellite for 15 years after launch.

radar-imaging-satellite-risat-lg.jpg

 

The satellite would be used for disaster prediction and

agriculture forestry, and the high resolution pictures and

microwave imaging could also be used for defence purposes.

 

Apr 12, 2012 Spacewar.com (IANS)

 

Chennai, India - The Indian rocket that will carry the 1,850 kg indigenous surveillance satellite - Radar Imaging Satellite (Risat-1) - to the skies this month will be controlled by the new mission control centre at Sriharikota, said a senior official of Indian space agency ISRO.

 

"The second mission control centre was inaugurated by President Pratibha Patil this January. The forthcoming rocket launch would be controlled and monitored from the new mission control centre. The rocket will fly off the first launch pad," S. Satish, director (publications and public relations), Indian Space Research Organisation (ISRO), told IANS.

 

ISRO has its rocket port at Sriharikota in Andhra Pradesh around 80 km from here.

 

A senior ISRO official not wanting to be named told IANS: "The new mission control centre is modern and has larger area to accommodate more space scientists, officials, VIPs and others."

 

ISRO officials told IANS that the rocket Polar Satellite Launch Vehicle (PSLV) carrying remote sensing satellite Risat-1 is slated for launch from April 25-30.

 

"The exact launch date depends on the readiness of the rocket and satellite systems. Normally it will take 12-14 days for the rocket launch after carrying out all the tests," an ISRO official told IANS.

 

ISRO officials told IANS that Risat-1 systems are being checked at Sriharikota and it will be mated with the rocket later.

 

Once the satellite is loaded on to the rocket, the entire rocket systems would again be tested.

 

The PSLV rocket is in a fully assembled condition and is waiting for Risat-1, the heaviest microwave remote sensing satellite to be built by India. The satellite has all weather, day and night imaging capability.

 

The satellite would be used for disaster prediction and agriculture forestry, and the high resolution pictures and microwave imaging could also be used for defence purposes.

 

The satellite's synthetic aperture radar (SAR) can acquire data at C-band. In 2009, ISRO had launched 300 kg Risat-2 with Israeli built SAR enabling earth observation in all weather, day and night conditions.

 

Remote sensing satellites send back pictures and other data for use. India has the largest constellation of remote sensing satellites in the world providing imagery in a variety of spatial resolutions, from more than a metre ranging up to 500 metres, and is a major player in vending such data in the global market.

 

According to ISRO officials, the rocket that would sling Risat-1 would be PSLV's upgraded variant called PSLV-XL.

 

The rocket would weigh around 320 tonnes at lift-off and would be the third such expendable rocket to be sent up by ISRO.

United Launch Alliance Delta IV Rocket Successfully Launches Payload for the National Reconnaissance Office

 

VANDENBERG AIR FORCE BASE, Calif. --- A United Launch Alliance (ULA) Delta IV rocket carrying a payload for the National Reconnaissance Office (NRO) lifted off from Space Launch Complex-6 here at 4:12 p.m. PDT today. Designated NROL-25, the mission is in support of national defense.

 

"Congratulations to the NRO and to all the mission partners involved in this critical national security launch," said Jim Sponnick, ULA vice president, Mission Operations. "ULA is proud to have supported this mission and delivered critical capabilities to the men and women defending our freedom throughout the world."

 

NROL-25 represents the first of five National Security Space missions that will be launched by the EELV program over the next four months - including four NRO missions along with the upcoming AEHF-2 launch.

 

This mission was launched aboard a Delta IV Evolved Expendable Launch Vehicle (EELV) Medium-plus 5,2 configuration vehicle, using a ULA single common booster core powered by a Pratt & Whitney Rocketdyne RS-68 main engine, along with two Alliant Techsystems GEM 60 solid rocket motors. The five-meter diameter upper stage was powered by a PWR RL10B-2 engine with the satellite encapsulated in a five-meter diameter composite payload fairing. This was the first launch of this Delta IV vehicle configuration.

 

Developed by the United States Air Force to assure access to space for Department of Defense and other government payloads, the EELV Program supports the full range of government mission requirements, while delivering on schedule and providing significant cost savings over the heritage launch systems.

 

ULA's next launch is the Atlas V AEHF-2 mission for the U.S. Air Force scheduled in early May from Space Launch Complex-41 at Cape Canaveral Air Force Station, Fla.

 

ULA program management, engineering, test, and mission support functions are headquartered in Denver, Colo. Manufacturing, assembly and integration operations are located at Decatur, Ala., and Harlingen, Texas. Launch operations are located at Cape Canaveral AFS, Fla., and Vandenberg AFB, Calif.

U.S.-Air-Force-Space-Command.jpg

 

Mar 23, 2012 By Andrea Shalal-Esa/Reuters AviationWeek.com

 

WASHINGTON - New navigational satellites being built by Lockheed Martin are “on schedule, on target,” the head of U.S. Air Force Space Command said on Thursday, dismissing a new congressional report that cited an 18 percent cost increase on the program.

 

Air Force General William Shelton told a defense writers group that Lockheed’s Global Positioning System (GPS) III satellite program was doing well and was “not even close” to breaching cost thresholds that would trigger a mandatory notification to Congress under the Nunn-McCurdy law.

 

“There is no question in my mind that that program is going extremely well,” Shelton told defense writers on Thursday.

 

He said any cost increase on the first two developmental satellites likely stemmed from increased government requirements for the program, adding that unit costs for the first two satellites had not been finalized.

 

“It depends on what you pick as a baseline,” Shelton told reporters. “I understand that from a bean-counter perspective that it might look like an increase but I don’t see it that way. It’s still a development program.”

 

The congressional Government Accountability Office on Wednesday released a report that cited progress on U.S. military space programs after a decade of cost overruns and schedule delays, but said some spacecraft still faced rising costs.

 

The report said the first two GPS III satellites were already 18 percent over budget, which would drive their cost up to $1.6 billion from the $1.4 billion cost initially estimated.

 

Lockheed spokesman Michael Friedman said the GPS III program was making solid progress and remained on schedule to launch the first of up to 32 potential satellites in the new constellation in mid-2014.

 

“We are experiencing no technical show-stoppers and our program cost estimates remain within the original Air Force program office budget,” Friedman said.

 

He said the program had run into some challenges but had been able to resolve those issues using a full-sized, flight equivalent prototype of a GPS III satellite, avoiding the higher costs of redoing the satellites actually headed for launch.

 

Lockheed is under contract to build the first four GPS III satellites under cost-plus terms, which are typical for new weapons development programs, but the company has said it is open to moving to a fixed-price type of contract starting with the fifth satellite, which would shift the primary responsibility for any cost overruns to the company.

 

Sources familiar with the program said Lockheed and the Air Force were expected to negotiate a contract for the fifth and sixth satellites by the end of this year.

 

Shelton said the Air Force was also moving ahead with plans to launch the new GPS satellites two at a time on a single rocket, which would halve the high cost of launching the satellites into space.

23/03/2012 Domitille Bertrand - DGA

 

À la pointe du renseignement d’origine électromagnétique (ROEM), le projet Ceres (capacité de renseignement électromagnétique spatiale) a pour objectif de détecter, localiser et caractériser depuis l’espace les signaux envoyés par les systèmes adverses, notamment les émetteurs de télécommunications et les radars. Alors que les satellites du projet Elisa, l’un des démonstrateurs qui visent à préparer Ceres, viennent d’être lancés, une équipe de la direction générale de l’armement (DGA) travaille sur le programme opérationnel qui doit être mis sur orbite à la fin de la décennie.

 

« Imaginons que vous soyez dans un lieu même isolé ou désertique, et que vous mettiez en fonctionnement un radar, celui-ci va émettre un signal. Les trois satellites du programme Ceres, volant en formation dans l’espace, vont passer au-dessus de votre zone et détecter les signaux émis. Ceci est valable pour tout type d’émetteur électromagnétique, qu’il s’agisse d’émetteurs de télécommunications ou de radars », explique Laurent Boniort, directeur du programme Segment Sol d’Observation et manager de l’opération d’armement Ceres à la DGA.

 

Détecter, localiser puis caractériser…

 

C’est l’utilisation simultanée des trois satellites positionnés « en triangle » qui permet de localiser l’émission. « Quand un radar émet un signal, chacun des satellites reçoit ce signal à un instant légèrement différent. C’est en croisant les informations recueillies par chacun et comparant l’heure de réception d’un même signal que l’on peut ainsi situer l’emplacement de l’émetteur : en comparant l’heure de réception du signal par deux satellites, la localisation de l’émetteur est imprécise car elle est matérialisée par une ellipse sur la Terre. En faisant l’exercice pour chaque « paire » de satellites (satellite 1/satellite 2 - satellite 1/satellite 3 - satellite 2/satellite 3), on aboutit à une localisation très précise. D’où la nécessité de disposer de trois satellites travaillant conjointement. »

 

Une fois l’émission détectée, puis localisée, il faut ensuite en définir les caractéristiques : quelle est la fréquence utilisée, est-elle fixe ou saute-t-elle périodiquement pour être plus discrète, le type de modulation choisie, etc. « Attention, nous n’écoutons pas le contenu des communications, nous détectons seulement les signaux ! » indique Laurent Boniort, qui précise : « si l’on veut intercepter le contenu de l’émission, il faut disposer d’un capteur qui reste longtemps sur la zone d’intérêt, et ce n’est pas le cas avec  Ceres : ce n’est pas comme dans les films hollywoodiens ! »

 

… Pour mieux surveiller et protéger

 

L’intérêt de ce programme est multiple. Avant tout, la capacité de surveillance est étendue : toutes les zones du monde sont observables par satellite sans contraintes d’accès, ce qui n’est pas le cas avec un bateau ou un aéronef. « En termes de protection, le fait de connaître les caractéristiques et les performances d’un radar adverse permet à un aéronef de le brouiller, par exemple. À l’inverse, on pourra également empêcher les radars ennemis de repérer l’un de nos aéronefs ou missiles, en les faisant évoluer hors des couvertures radar adverses. » Au delà des applications purement militaires, le programme Ceres étant conçu pour pouvoir analyser les différents types d’émissions, il permettra, en plus de déterminer l’architecture de systèmes en réseaux, tel des réseaux de communication, de suivre, en fonction des caractéristiques des signaux, l’évolution du niveau des performances des matériels des forces adverses. « En d’autres termes, il pourra détecter la prolifération de matériels sophistiqués dans une zone d’intérêt, si besoin est. »

 

La France est le seul pays européen présent sur ce domaine, rejoignant ainsi le club, très fermé, des pays les plus avancés dans le renseignement d’origine électromagnétique, avec principalement les États-Unis et la Russie.

GeoEye Concept

 

Mar 21, 2012 By Angus Batey - defense technology international

 

London - Maps are clearly a vital tool for any military commander, but the days when a two-dimensional, printed representation of an area will suffice have long since passed. Dynamic mapping of the battlespace is not new, but 21st century technologies are revolutionizing the collection, dissemination and analysis of tactical intelligence.

 

At Defense Geospatial Intelligence here in January, the annual conference for the defense and security geoint community, participants mulled technologies and techniques from simple refinements to enable easier comprehension of an area of operations, to radical concepts intended to predict events based on analysis of patterns in fused geolocated data sets.

 

Col. Mark Burrows, commander of the U.K.’s Joint Aeronautical and Geospatial Organization, explained that recent experience has highlighted crucial areas in which geoint operators have to upgrade their skill sets. “We didn’t really do geospatial business very well in urban areas in the past,” Burrows says. Pointing to a photograph of high-rise tower blocks next to villages, he says it is “the sort of thing we’re going to have to put on a map” but in a way that can be understood. “It’s probably going to be in 3-D, I suspect, especially if you were a helicopter pilot and needed to know how to fly through it. We have the scope to do rapid 3-D modeling, but we need to find a way to get that in the field quickly. Another one is littoral [operations]. We will have to do it again, we may have to do it at very short notice, and we are going to have to work onboard ships a bit more.”

 

Libya quickly is turning into a classic case. “Timelines were very dynamic in Libya,” recalls Cpl. Ross Colwell, a geo support sapper who was deployed to support Apache crews and Royal Navy personnel on board HMS Ocean. “The main product I created was the rebel frontline; it could change by the hour, so I had to get products out pretty much as soon as I could get them, generally within half an hour. On board HMS Ocean the distribution of products was quite simple—mainly it was hard copy. But we require improved dissemination techniques [to send products off-ship].”

 

Indeed, while historically geoint has been land-based, the maritime domain is becoming an increasingly important geoint domain, driven by the resurgence of piracy, which brings greater urgency to the need for accurate intelligence about shipping movements. Also, year-round access to formerly ice-bound shipping routes demands real-time updates and high-grain detail to enable safe passage through constantly changing sea lanes.

 

The Italian company e-Geos, owned jointly by Finmeccanica and Thales, can collect two complete sets of images of the Northwest Passage within 17 hr. from its Cosmo-SkyMed satellite constellation. Analysis of images taken minutes apart can help calculate the speed of the movement of ice and thus aid route prediction.

 

ExactEarth of Cambridge, Ontario, has built a lower-orbiting constellation specifically to map shipping movements over oceans. At 30 km (18.6 mi.) the satellites can receive signals from shipboard Automatic Identification Systems (AIS), enabling real-time intelligence on any vessel deviating from its planned route, and flagging the location of ships that have their AIS turned off.

 

The benefits of geoint are also apparent to homeland security and police forces. GeoEye of McLean, Va., a supplier of satellite imagery, acquired the predictive analysis company Spadac in 2010 and now supplies more than 40 customers with predictive geospatial intelligence. The software analyzes geo-tagged data to discover relationships between events and features in the physical and human environment; a proprietary algorithm then predicts future occurrences. The company has demonstrated prediction of phenomena as varied as burglaries and the arrival of invasive species.

 

Geoint is also an area that seems particularly open to innovations from outside the traditional defense establishment. Santa Clara, Calif. -based Nvidia, known for high-speed graphics processing cards used mainly to improve the game-playing power of consumer PCs, says its cards are a good fit for the intensive data processing frequently found in geoint tasks. Not only could the processing power assist in enhancement of imagery received at a base station, but exponential increases in processing capability on board a satellite or UAV could speed up intelligence dissemination by ensuring only the most relevant imagery is sent down to the ground.

La surveillance de l’espace, base indispensable d’une défense spatiale


26/03/2012 Commandant Thierry Cattaneo  - CDAOA

 

Parler de spatio-dépendance des sociétés modernes et de leurs armées n’est certes plus original, mais les menaces induites, invisibles, sont encore sous-évaluées. C’est pourquoi le Livre blanc sur la défense et la sécurité nationale affirme : « La surveillance de l’espace est devenue un grand enjeu civil et militaire. »

 

Surveiller l’espace est une nécessité reconnue, et la France se dote progressivement d’outils lui permettant d’apprécier les éléments les plus pertinents de la situation spatiale de façon autonome. Encore faudra-t-il définir les concepts et doctrines, acquérir les justes moyens et savoir-faire, mettre en œuvre les logiques et monter les structures éventuellement capables de modifier cette situation, si l’on souhaite évoluer du spatial de défense à la défense spatiale.

 

L’importance des moyens spatiaux

Il est illusoire désormais d’espérer agir sans le support des satellites. Ainsi, le GPS n’est pas seulement ce service qui permet de guider la munition ou de positionner précisément les unités, et dont, au prix d’une augmentation du risque, on pourrait se passer ; il est aussi et avant tout le fournisseur d’une horloge extrêmement précise sur laquelle sont calées de nombreuses applications, comme les réseaux informatiques, la téléphonie ou les échanges interbancaires. Réduire cette dépendance stratégique impose la possession en propre d’un service équivalent : Galileo. De même, pour les liaisons à longue distance entre métropole et éléments déployés, il est courant de réserver des créneaux et fréquences sur des satellites de communication.

Toutefois, les segments spatiaux sont exposés à tout un spectre de menaces :

  • naturelles au travers de l’environnement et de sa météorologie particulière ;
  • artificielles par le nombre et le caractère incontrôlable des débris ;
  • ou encore volontaires comme le montrent les tirs antisatellites (ASAT) opérés à titre de démonstration par les Américains et les Chinois.

 

Surveiller, contrôler, protéger

Il est donc nécessaire à plus d’un titre pour une puissance spatiale de surveiller la situation exo- atmosphérique, et de maîtriser ce qui s’y déroule, pour s’en protéger selon des modes passifs ou actifs. De plus en plus, les États cherchent à exercer leur influence dans l’espace, pour en tirer un bénéfice notamment militaire. Dans ce domaine, la Défense française développe progressivement les moyens, les savoir-faire et la visibilité qui lui permettent de tenir son rang parmi les leaders mondiaux.

L’armement cinétique anti-satellites est aujourd’hui proscrit par le légitime souci de préservation de l’espace. D’autres modes d’action, moins destructifs ou tournés vers les segments sol de commandement ou contrôle, sont désormais envisagés. De plus, à la dématérialisation de la menace peut répondre une dématérialisation de la contre-mesure : cyber-attaques, actions de guerre électronique peuvent s’avérer particulièrement efficaces. Si ces moyens sont aujourd’hui virtuellement disponibles, les cadres d’action restent à définir. Et cette guerre spatiale, dont le plus gros de l’engagement se déroulera paradoxalement au sol, ne pourra reposer que sur des personnels spécifiquement formés.

 

La coopération CNES - CDAOA

Le CNES et l’armée de l’air coopèrent activement en vue de la préservation et du meilleur emploi des moyens spatiaux nationaux, se partageant les manœuvres, la programmation et la surveillance de la situation. Ce lien est particulièrement valorisé en cas de risque de collision et pour la surveillance des rentrées atmosphériques d’objets potentiellement dangereux en raison de leur masse ou de leur composition.

Les résultats obtenus sont comparables à ceux que communique la NASA.

Chacun des deux organismes œuvre en respectant des cadres légaux fixés par la loi sur les opérations spatiales et par le code de la défense.

Risat-1.-Photo-Credit-ISRO.jpg

 

Mar 13, 2012 by Venkatachari Jagannathan(IANS) Source: Indo-Asia News Service

 

Chennai, India - A wholly Indian-built spy/surveillance satellite - Radar Imaging Satellite (Risat-1) - that can see through clouds and fog and has very high- resolution imaging is slated for launch in April, a senior official of the Indian space agency has said.

 

An official of the Indian Space Research Organisation (ISRO) said thorough tests were being done on the Risat-1. "The Risat-1 is put to thermal vacuum test (a test to check the satellite's functioning in space environment). It is a complex microwave satellite being built for the first time in India. The satellite is expected to be launched in April," the senior official told IANS, not wishing to be named because of the organisational rules.

 

In earlier satellites, one major component, the synthetic aperture radar (SAR) was imported, but in Risat-1 that has also been developed in India.

 

He said Risat-1 is the first such satellite being built by India and is a bit complex compared to other remote sensing/earth observation satellites built and sent up earlier.

 

According to ISRO officials, Risat-1 at 1,850 kg is the heaviest microwave satellite to be built by India.

 

The satellite would be used for disaster prediction and agriculture forestry, and the high resolution pictures and microwave imaging could also be used for defence purposes.

 

Risat-1 will have all weather, day and night imaging capability.

 

The satellite's synthetic aperture radar can acquire data at C-band.

 

ISRO Chairman K. Radhakrishnan had said last October that the space agency would launch two more satellites - Risat-1 and SARAL - before 2011-end. But that did not happen. He also said two more satellites - AstroSat and Aditya - will be launched in 2012-13.

 

Remote sensing satellites send back pictures and other data for use. India has the largest constellation of remote sensing satellites in the world providing imagery in a variety of spatial resolutions, from more than a metre ranging up to 500 metres, and is a major player in vending such data in the global market.

 

In 2009, ISRO had launched 300 kg Risat-2 with an Israeli built SAR enabling earth observation on all weather, day and night conditions. The satellite can look through clouds and fog.

 

With 11 remote sensing/earth observation satellites orbiting in the space, India is a world leader in the remote sensing data market. The 11 satellites are TES, Resourcesat 1, Cartosat 1, 2, 2A and 2B, IMS 1, Risat-2, Oceansat 2, Resourcesat-2, Megha-Tropiques.

 

According to ISRO officials, the rocket that would sling Risat-1 will be the Polar Satellite Launch Vehicle's (PSLV) upgraded variant called PSLV-XL.

 

The rocket would weigh around 320 tonnes at lift-off and will be the third such expendable rocket to be sent up by ISRO, and first time to launch a remote sensing satellite.

 

ISRO had used the PSLV-XL variant (rocket with extended strap-on motors than what the base model has) for its moon mission (Chandrayaan-1) in 2008 and for launching its communication satellite GSAT-12 in 2011.

 

The PSLV is a four-stage (engine) rocket powered by solid and liquid propellants alternatively. The first and third stages are fired by solid propellant and the second and fourth stages are fired by liquid propellant.

 

ISRO has developed three PSLV variants. The first is the standard variant weighing around 290 tonnes with six strap-on motors measuring 11.3 metres with a fuel capacity of nine tonnes.

 

The other two rocket variants are the PSLV Core Alone without the six strap-on motors and PSLV-XL with longer strap-on motors measuring 13.5 metres having a fuel capacity of 12 tonnes of solid fuel.

Space-Fence-radar-system--Lockheed-Martin.jpg

 

Mar 8, 2012 ASDNews Source : Lockheed Martin Corporation

 

A prototype of a new radar system developed by a Lockheed Martin -led team is now tracking orbiting space objects, bringing the U.S. Air Force’s Space Fence program one step closer to revolutionizing our nation’s space situational awareness.

 

Utilizing powerful, new ground-based radars, Space Fence will enhance the way the U.S. detects, tracks, measures and catalogs orbiting objects and space debris with improved accuracy, better timeliness and increased surveillance coverage. Lockheed Martin’s prototype radar recently met a key contract requirement during a series of demonstration events by proving it could detect these resident space objects, as they are referred to by the Air Force.

 

On February 29, the Air Force granted its final approval of Lockheed Martin’s preliminary design for the system.

 

“The successful detection and tracking of resident space objects are important steps in demonstrating technology maturity, cost certainty and low program risk,” said Steve Bruce, vice president of the Space Fence program at Lockheed Martin’s Mission Systems & Sensors business. “Our final system design incorporates a scalable, solid-state S-band radar, with a higher wavelength frequency capable of detecting much smaller objects than the Air Force’s current system.”

 

Space Fence will enable the decommissioning of the aging U.S.-based Air Force Space Surveillance System (AFSSS), originally installed in 1961. With more than 60 nations operating in space today, the final frontier is much more complex than when the AFSSS first started tracking a few hundred orbiting objects. Today, with hundreds of thousands of objects orbiting the earth, space debris and risk of potential collisions now threaten national space assets providing critical services, including the Global Positioning System, banking and telecommunications.

 

Bruce added, “Space Fence will detect, track and catalog over 200,000 orbiting objects and help transform space situational awareness from being reactive to predictive.  The Air Force will have more time to anticipate events potentially impacting space assets and missions. Our net-centric design approach allows Space Fence to be easily integrated into the broader U.S. Space Surveillance Network of sensors already operated by the Air Force.”

 

Lockheed Martin’s Space Fence prototype was developed under an 18-month, $107 million contract awarded by the Air Force in January 2011.  The Air Force has said it plans to award a Space Fence production contract later in 2012.   The first of several Space Fence sites is expected to reach initial operational capability in 2017.

 

With more than 400 operational S-band arrays deployed worldwide, Lockheed Martin is a leader in S-band radar development, production, operation and sustainment. The Lockheed Martin-led team -- which includes General Dynamics, AMEC and AT&T -- has decades of collective experience in space-related programs, including sensors, mission processing, cataloging, orbital mechanics, net-centric communications and facilities.

07/03/2012 DGA

 

Gérard Longuet, ministre de la défense et des anciens combattants, a annoncé le 6 mars 2012 que la direction générale de l’armement (DGA) venait de renouveler le marché de maintien en condition opérationnelle de la composante terrestre « utilisateurs » du système spatial d'observation optique.

 

La direction générale de l’armement (DGA) a notifié ce contrat à la société Astrium le 23 février 2012 au nom des 5 pays partenaires du programme que sont la France, la Belgique, l’Espagne, l’Italie et la Grèce. D’une durée d’un peu plus de 6 ans,  le marché s'élève à 204 millions d'euros TTC. Il prend en compte également les équipements allemands couverts par l'accord d'échange d'images satellite entre la France et l'Allemagne.

 

Hélios 2 est constitué des 2 satellites, baptisés 2A et 2B, lancés respectivement en 2004 et 2009. Ceux-ci sont programmés à partir d'un centre de maintien à poste situé à Toulouse et à partir de centres nationaux d'élaboration des plans de prise de vues et de réception des images. Le contrat concerne les 6 centres nationaux et couvre le remplacement des matériels obsolescents, les évolutions logicielles ainsi que la maintenance du système et le support aux utilisateurs.

 

Le système d’imagerie spatiale Helios 2 répond aux besoins de la France et de ses partenaires dans le domaine du renseignement de défense et de sécurité. Il est caractérisé par sa couverture mondiale, sa capacité de survol permanente et conforme au droit international, et la répétitivité de ses prises de vue. Les satellites Hélios 2 permettent l'identification de signes précurseurs de crise, de menaces terroristes, la conduite d'opérations militaires sur des théâtres éloignés (préparation de mission, repérage d’objectifs) et la vérification du respect des traités de désarmement et de non prolifération.

 

Hélios 2 assure depuis 2005 la continuité de service fourni initialement par Hélios 1, système de première génération réalisé par la France, l’Italie et l’Espagne, opérationnel à partir de 1995 et dont le dernier satellite (Hélios 1A) a été désorbité en janvier 2012.

Galileo-ETCA-satellites-source-Esa.jpg

 

29 February 2012 Thales Alenia Space ETCA

 

Charleroi, 29th February 2012 - Thales Alenia Space ETCA, a subsidiary of Thales Alenia Space based in Charleroi, received an order from the German company OHB System to supply eight electronic modules for the last eight satellites in the Galileo* constellation. This additional batch of satellites is designed and manufactured by OHB System, industrial prime contractor for the space segment.

 

As part of the Fully Operational Capability (FOC) phase, the Belgian subsidiary has already signed a contract with OHB System to provide a Power & Distribution Conditioning Unit (PCDU) for each of the first 14 satellites in the constellation.

 

Thales Alenia Space ETCA is to design and deliver the Power Conditioning and Distribution Units, more commonly known as electrical cores. They supply power to all the satellites’ equipment and instruments, from the two power sources on board: the photovoltaic solar panels and the batteries during solar eclipses.

The PCDU will also manage the storage of the excess power produced by the solar panels in the satellites’ batteries.

 

According to Patrick Bury, Commercial and Programmes Manager at Thales Alenia Space ETCA: “This order represents 30,000 working hours for our company and strengthens our position as European leader in power distribution and management on board satellites.”

 

Galileo is the European programme for developing a global satellite navigation system. Applications will include maritime, air and land transport, emergency operations, public works and agriculture.

 

After the launch of the Giove-A and Giove-B test satellites in 2005 and 2008, and of the two pairs of In-Orbit Validation (IOV) satellites, the first of which was launched in October 2011, the Full Operational Capability (FOC) phase will be deployed, making a total of 30 satellites in the final configuration of this constellation.

 

An active participant in satellite navigation systems

The French, Italian, Spanish and Belgian sites of Thales Alenia Space have also long played a crucial part in developing the Galileo system and its predecessor, EGNOS:

 

Thales Alenia Space has been an important partner in the Galileo program since the beginning, with the ground-segment Galileo System Test Bed (GSTB) in 2003 and as lead subcontractor for the GIOVE-B demonstrator, launched in 2008. As prime contractor for assistance to the Galileo system, Thales Alenia Space provides ESA with industrial support for the system covering the engineering, performance, assembly, integration and validation of the system, and the engineering for the space signal, security and product assurance. Thales Alenia Space is also prime contractor for the development and deployment of the Galileo Mission Segment (GMS) and the Galileo Security Facility (GSF) which will control the entire navigation system from the ground. In addition, Thales Alenia Space will provide the signal generation units and antennas, two critical components of the navigation payload for the first 14 satellites to begin the deployment of the constellation to full operational capability (FOC).

 

For the four Galileo satellites of the IOV phase, Thales Alenia Space ETCA supplied the transmitter units that enable the satellites to communicate with the operators on the ground for remote control and telemetry. Thales Alenia Space ETCA also coordinated the various subcontractors that each build part of the hardware and software needed for these units. With the assistance of SSBV, Thales Alenia Space ETCA also designed and manufactured the benches for testing and validating the transmitter units before the four IOV satellites are launched.

 

The definition and development phase and IOV phase of the Galileo programme were conducted by ESA and co-funded with the European Commission.

 

*The Full Operational Capability phase of the Galileo programme is managed and fully funded by the European Union. The Commission and ESA have signed a delegation agreement by which ESA acts as design and procurement agent on behalf of the Commission. The views expressed in this Press Release can in no way be taken to reflect the official opinion of the European Union and/or ESA."Galileo" is a trademark subject to OHIM application number 002742237 by EU and ESA.

 

 

Thales Alenia Space In Belgium

Thales Alenia Space ETCA is the largest Belgian manufacturer of space electronics and the World leader in satellite power supplies. The company is also the foremost supplier of electronics for the Ariane 5 satellite launcher. Almost 600 people work at its Mont-sur-Marchienne site.

Gérard Longuet chez Astrium et Thales Alenia Space pour renforcer les liens entre défense et spatial

G. Longuet, ministre de la Défense et F. Auque, PDG d'Astrium

 

06/03/2012 Wilfried Pinson — ObjectifNews.com

 

Le ministre de la Défense, Gérard Longuet, était aujourd’hui à Toulouse. Il a visité les sites d’Astrium et de Thales Alenia Space et réaffirmé l’importance des liens entre la défense et le spatial. Lors de son discours à la Chambre de commerce et d'industrie, Gérard Longuet a notamment annoncé le renouvellement du marché d'Hélios-2 de 204 millions d'euros.

 

« Le sens de ce déplacement chez Astrium se trouve dans les liens entre la défense et l’espace », a souligné Gérard Longuet, ce mardi à Toulouse. Le ministre a pu en avoir l’illustration en débutant par une visite chez Astrium. En début d’après-midi, il a assisté à la démonstration de « Spirale » (dont Thales Alenia Space est maître d'oeuvre) , un système d’alerte par satellites qui permet de détecter les tirs de missiles. Puis rapidement, Astrium lui a présenté Gaia,  un satellite doté d’immenses miroirs qui doit permettre de cartographier la galaxie en 3D pour le compte de l’Agence spatiale européenne (Esa).

 

Gérard Longuet s’est ensuite attardé dans la salle des satellites de télécommunication où se déroulent l’assemblage et les tests finaux. Le ministre a écouté les explications de François Auque, PDG d’Astrium. La visite s’est terminée dans la salle « Alecoïde »,  sorte de "simulateur d’infini" qui permet de tester les signaux des satellites. Le ministre a souligné alors « la très  forte implication »  du secteur de la défense dans le spatial. Avant de réagir à la vue d'une photo de Paris prise par un satellite, la commentant d'un « C’est très joli, il y a une vue sur les jardins de l’Élysée… »

 

La visite s’est ensuite poursuivie chez Thales Alenia Space où des systèmes de télécommunication par satellites lui ont été présentés.

 

Un marché de 204 millions d'euros renouvelé

 

Gérard Longuet s’est également exprimé sur la lettre de Peter Hintze, coordinateur de l'aéronautique et de l'espace pour le gouvernement allemand, qui a récemment écrit au futur président exécutif d'EADS Tom Enders au sujet du déplacement du siège du groupe à Toulouse. « Je serais un élu local allemand, sans doute aurai-je cette réaction. Quand on a un  grand projet européen à l'image d'EADS, certes de culture française, mais de dimension mondiale avec une assise européenne, il faut dépasser cela. Le choix de Tom Enders est l'expression de la simplicité, de l’efficacité et je dirai en termes opérationnels de bon sens. Les Allemands n'en manquent pas, je pense qu'ils seront de nouveau en accord avec nous », a affirmé le ministre.

 

Gérard Longuet a ensuite prononcé un discours à la CCI Toulouse 31. Il a annoncé le renouvellement du marché de maintien en condition opérationnelle d'Hélios 2, système spatial d'observation optique pour le domaine militaire. Ce marché, attribué à Astrium, se chiffre à 204 millions d'euros pour une durée de six ans. Le programme  européen MUSIS, un système d'observation qui nécessite trois satellites recevra également un "appui substantiel" du ministère de la Défense. Deux des satellites nécessaires devraient pouvoir être terminés grâce à cette aide. Gérard Longuet a finalement évoqué un environnement international de plus en plus concurrentiel qui demande une coopération renforcée au plan européen.

06/03/2012 LeFigaro.fr (AFP)

 

Astrium continuera à assurer le maintien en conditions opérationnelles du système satellitaire d'observation militaire Hélios 2, un contrat de 204 millions d'euros, a annoncé le ministre de la Défense Gérard Longuet aujourd'hui à Toulouse.

 

Le contrat dont le ministre a annoncé la reconduction concerne le segment sol du système et couvre la période 2012-2018. Il permettra d'assurer le lien avec le successeur d'Hélios.

 

Hélios est un système aujourd'hui composé de deux satellites actifs et d'une composante terrestre, et développé sous maîtrise d'oeuvre d'Astrium, première entreprise spatiale européenne et filiale d'EADS. La deuxième génération d'Hélios, Hélios 2, est un programme réalisé en coopération entre la France, la Belgique, l'Espagne, l'Italie et la Grèce.

 

Hélios 2 sert par exemple à la vérification du respect des traités de désarmement ou à l'identification des signes précurseurs de crise. Le maintien en conditions opérationnelles consiste dans l'ensemble des opérations conduites à partir du sol pour le bon fonctionnement, la maintenance et la mise à jour du système.

Musis va remplacer les satellites Hélios, lancés en deux

vagues, en 1995-1999 et 2004-2009.

 

06/03/2012 Par Véronique Guillermard- LeFigaro.fr

 

Le ministre de la Défense a rendu publics plusieurs contrats attribués à Astrium et Thales Alenia Space.

 

La collecte de renseignements militaires depuis l'espace est une priorité pour la France. Les satellites d'observation, d'écoute ou d'alerte avancées jouent et joueront de plus en plus un rôle clef dans les processus de décision, la préparation et la conduite des missions opérationnelles sur le terrain.

 

La France veut tenir son rang de grande puissance dans l'espace en se dotant d'une nouvelle génération de satellites d'écoute militaire tout en évitant toute rupture capacitaire avec l'existant, c'est-à-dire la flotte des trois satellites d'observation de la famille Hélios.

 

Gérard Longuet a rendu publiques mardi, en marge d'un déplacement à Toulouse chez Astrium, filiale spatiale d'EADS, et de Thales Alenia Space (TAS), filiale de Thales et de Finmeccanica, trois décisions prises le matin même au cours d'un Comité ministériel d'investissements.

 

Elles donnent un coup d'accélérateur à Musis et Ceres, le premier prenant le relais d'Hélios, le second dotant la France de satellites de renseignement électromagnétique capables de repérer les émissions radars de zones mises sous surveillance.

 

Le ministre de la Défense a annoncé le bouclage du financement des satellites successeurs d'Hélios. Quelque 400 millions d'euros sur un total de 795 millions seront mobilisés pour achever la construction de deux satellites d'observation, réaliser le segment sol et lancer les satellites en 2016 pour une mise en service en 2017. Le Cnes doit notifier cette ultime tranche du contrat à Astrium, maître d'œuvre en charge de la plate-forme et de l'avionique des deux satellites, et à TAS, responsable de la conception et de la fabrication de l'instrument optique.

Contrat de maintenance d'Hélios

 

En bouclant ce financement, la France réaffirme, malgré la crise, son engagement dans le futur système de renseignements européen Musis dont il fournit la composante de reconnaissance optique. L'Allemagne et l'Italie doivent fournir le système de reconnaissance par radar qui prendra le relais des satellites Sar-Lupe et Cosmo-SkyMed qui arrivent en fin de vie en 2017.

 

En attendant, il est impératif de maintenir en condition opérationnelle les satellites Hélios lancés en deux vagues en 1995-1999 et 2004-2009. La France a renouvelé le contrat de maintenance de la composante terrestre du système Hélios au nom des cinq pays partenaires (France, Belgique, Espagne, Italie et Grèce), a annoncé Gérard Longuet. Le contrat, d'une valeur de 204 millions d'euros, court sur six ans et a été attribué à Astrium.

 

Le ministre de la Défense a également donné une impulsion au programme Ceres. La Direction générale de l'armement doit engager les premières études et définir les spécifications du futur satellite dans la perspective d'une mise en orbite en 2020. Enfin, en matière d'alerte avancée (détection du lancement d'un missile balistique), les premières études doivent être lancées.
