EDA And ESA Sign DeSIRE II Project Arrangement

Brussels - 06 February, 2014 European Defence Agency


Through their 2011 Administrative Arrangement and active policy and programmatic coordination, the European Defence Agency (EDA) and European Space Agency (ESA), have today agreed to pursue their cooperation in the domain of Remotely Piloted Aircraft Systems (RPAS) with the signature of the DeSIRE II Project Arrangement.

This cooperation is the result of the successful DeSIRE I project carried out in 2012 and 2013, through which EDA and ESA demonstrated the use of satellites enabling the insertion of RPAS in Europe. This project effectively demonstrated that RPAS complemented by satellites can be safely inserted in non-segregated airspace and thus fulfil user needs in maritime surveillance services.

Following respective approval processes, EDA’s Chief Executive Claude-France Arnould and Magali Vaissiere, ESA Director of Telecommunications and Integrated Applications, have today concluded the signature of the next step of this cooperation. DeSIRE II will demonstrate that services, such as environment and maritime surveillance applications, can be rendered with RPAS flying beyond radio line of sight through the use of safe and secure satellite-based command and control data links. 

This demonstration project will also seek to illustrate the benefits of the integration of space assets, such as communication satellites, navigation satellites and Earth observation satellites, with terrestrial infrastructure for enabling new services. It will further tackle the implementation of an initial set of elements for air traffic management and related safety issues in order to support the evolution of air traffic insertion regulations and standards.

DeSIRE II is expected to be a bridging phase towards more cooperation between ESA and EDA on RPAS applications and capability developments.

Selex Cyber Team Receives Galileo PRS IOV Signal

July 11, 2013 Source: Selex ES


Selex ES Cyber Security Team Successfully Receives Galileo PRS IOV Signal


Selex ES has successfully proved itself able to work with the secure signal radiated by Galileo satellites. Just days after the European Space Agency (ESA) made available the keys to "open" the encrypted Galileo PRS (Public Regulated Service), the PRS receiver "Cartesio", fully developed by Selex ES, proved to work successfully.


Selex ES Cyber Security team achieved the first navigation solution using only the encrypted Galileo Public Regulated Service (PRS) signals, with a positioning accuracy compliant to the specification. The use of the PRS signal is restricted to EU and other authorized countries government agencies and critical infrastructures. Anti-spoofing and interference rejection capabilities are PRS main features, due to the very sophisticated signal processing and high-grade encryption techniques.


Selex ES is the first company to have developed the PRS know-how outside the ESA contracts and without the continuous support of the Galileo system architects. This was the roadmap of the Cartesio achievements:

-- Demonstration to Italian Authority representative in the Genoa Laboratory of the PRS signal acquisition and tracking on 19th July 2012;

-- Successful reception and processing of the PRS Signal-in-Space on 14th June 2013, two days after the IOV keys were made available by ESA;

-- Achieving the PRS-only navigation solution on 4th July 2013.


Cartesio has been approved for use under IOV testing by the National Security Agency and the Italian Competent PRS Authority asked to make it available for the “PRS Participants Trial for IOV” (PPTI) framework, including both laboratory verifications and trials with governmental users.


The receiver is the first member of a product family but already integrates Galileo OS and GPS SPS capabilities, to extend the field testing windows.

Galileo Spreads its Wings

Jul 11, 2013 ASDNews Source : European Space Agency (ESA)


Deployment of the solar wings on the latest Galileo satellite is shown being checked at ESA’s technical hub in the Netherlands. The navigation satellite’s pair of 1 x 5 m solar wings, carrying more than 2500 state-of-the-art gallium arsenide solar cells, will power the satellite during its 12-year working life.


A counterweighted rig supports the deployment, otherwise the delicate fold-out wings – designed for the weightlessness of space – would crumple under the pull of Earth gravity.


With the first four Galileo ‘In-Orbit Validation’ satellites already in orbit, this is the first of the rest of Europe’s satnav constellation.


These ‘Full Operational Capability’ satellites provide the same operational services as their predecessors, but they are built by a new industrial team: OHB in Bremen, Germany build the satellites with Surrey Satellite Technology Ltd in Guildford, UK contributing the navigation payloads.


There are also a lot more of them: this satellite is only the first of 22 ordered from OHB. It arrived at ESA’s ESTEC research and technical centre in Noordwijk in mid-May to begin a rigorous campaign of testing in simulated launch and space conditions, guaranteeing its readiness for launch.


The very first test performed on the satellite once it came out of its container was a System Compatibility Test Campaign, linking it up with the Galileo Control Centres in Germany and Italy and ground user receivers as if it was already in orbit.


Galileo’s wings with 30%-efficient solar cells were fitted at the end of June, supplied by Dutch Space in nearby Leiden.


Future satellites will have their wings fitted at OHB before coming to ESTEC, but this first satellite offered an opportunity for Dutch Space engineers to train their OHB counterparts in the procedure.


“The 22 Galileo FOC satellites are being produced and tested on a batch production basis, which is a new way of working for ESA,” explained Jean-Claude Chiarini, overseeing FOC satellite procurement for the Agency.


“The concept is really to set up a steady flow of satellites from OHB to ESTEC and then Kourou for launch over the next few years.


“The first four will undergo full validation testing, checking the underlying design is correct, in order to support the formal ground qualification of the design, with subsequent FOC satellites then going through acceptance testing, concentrating on checking workmanship.”


The FOC satellites, while resembling their predecessors, are designed with this production concept in mind. Hinged modules offer easy access to internal subsystems for rapid repair or potential replacement of units.


The next satellite is due to arrive around the start of August. The battery of simulations includes vibration and acoustic testing, as well as thermal–vacuum testing – submitting them to the airlessness and temperature extremes of space for weeks at a time.

First new Galileo satellite arrives at ESA for space testing

May 17, 2013 ASDNews Source : European Space Agency


The first satellite of Galileo’s next phase has arrived at ESA’s technical heart in the Netherlands for a rigorous set of tests to check its readiness for launch.


This first Galileo Full Operational Capability – FOC – satellite is functionally identical to the first four Galileo In-Orbit Validation satellites already in orbit, the operational nucleus of the full Galileo constellation, but has been built by a separate industrial team.


Like all the other 21 FOC satellites so far procured by ESA, the satellite’s prime contractor is OHB in Bremen, Germany and the navigation payload was produced by Surrey Satellite Technology Ltd in Guildford, UK.


This first FOC satellite arrived by road at ESTEC’s Test Centre in Noordwijk, the Netherlands, on 15 May to undergo a series of tests simulating different aspects of launch and space environment. The comprehensive test programme will validate the new design and all the satellites to follow.


A unique facility for Europe, ESA’s test centre has all the facilities needed to validate a satellite for launch under a single roof.


Thermal vacuum testing will simulate the temperature extremes the satellites must endure in the airlessness of space throughout their 12-year working lifetimes. Without any moderating atmosphere, temperatures can shift hundreds of degrees from sunlight to shadow.


Other activities on the schedule include shaker and acoustic noise testing – simulating the vibration and noise of launch – as well as electromagnetic compatibility and antenna testing, placing the satellite in chambers shielded from all external radio signals to reproduce infinite space and check that its various antennas and electrical systems are interoperable without harmful interference.


Each satellite will offer the full range of Galileo positioning, navigation and timing services, plus search and rescue message relays, their accuracy ensured by onboard atomic clocks kept synchronised by a worldwide ground network.


“The Galileo FOC satellites provide the same capabilities as the previous IOV satellites, but with improved performance, such as higher transmit power,” explains Giuliano Gatti, the Head of the Galileo Space Segment Procurement Office. “They are to all intents a new design that requires a full checkout before getting the green light for launch.


“By fully validating this satellite, the second flight model due to follow it here at beginning of June, and the third one due to arrive in ESTEC at middle of July, we gain full knowledge of their characteristics, and the further satellites in the series will require less rigorous functional testing.”

Poland MoD


September 14, 2012 defpro.com


On Thursday, September 13, Polish Minister of National Defence Tomasz Siemoniak participated in the ceremony of signing European Space Agency Accession Agreement held in Copernicus Science Centre in Warsaw. The Minister of Economy Waldemar Pawlak and Jean-Jacques Dordain, ESA Director General signed the document.

Ratification of the document is planned for November 16 in order to enable Poland to participate in autumn talks on Agency's budget.

The Ministry of National Defence supports Poland's accession to ESA as it can see the prospects of using space technology by Polish Armed Forces. Poland's office of ESA will be subordinate to the Ministry of Economy. Representatives of Ministry of National Defence will join its structures as the majority of ESA activities are connected with security and defence.

Poland's membership in ESA will facilitate developing enterprises that have already started: building national capabilities within image reconnaissance and communication for public administration and uniform services, developing new armament and defence systems concerning observing the surface of the earth, command support and imaging of the battle field.

Poland's presence in ESA will also simplify cooperation within international projects that have already started e.g. - satellite defence agreement with Italy or participation in Multinational Space-based Imaging System for Surveillance, Reconnaissance and Observation (MUSIS).

Poland has been an ESA European Cooperating State since April 2007. At the moment there are 19 members of ESA: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Ireland, Italy, Luxembourg, the Netherlands, Norway, Portugal, Spain, Sweden, Switzerland, Romania and the United Kingdom. Canada takes part in some projects under a Cooperation agreement.
