Arianegroup, Eutelsat and Magellium selected to improve French space surveillance capabilities

ArianeGroup, Eutelsat and Magellium have won a contract from the French space agency (CNES), as part of the space component of the France 2030. Investing for the Future plan, with the aim of enhancing space surveillance capabilities in order to substantially improve the security of space operations.


The consortium will provide CNES with a Space Situational Awareness (SSA) data service through the deployment of multi-orbital optical sensors, and the development and implementation of an optical space segment in geostationary transfer orbit (GTO), to complement and enhance the performances of the existing ground-based network operated by ArianeGroup.


ArianeGroup is the prime contractor on this project and will supply the surveillance services provided by its ground-based network of telescopes, supplemented by data from the spaceborne sensor that will be developed during the project and then interconnected to ArianeGroup’s system. “This contract recognizes the quality and efficiency of the space surveillance services already provided by ArianeGroup to its government, institutional and private customers. It is also a vote of confidence in our ability to bring together the very best expertise, provided by partners with complementary skills. Developing sovereign space surveillance capabilities is a strategic priority for France and Europe. We are proud to contribute together to improving security in space, for the benefit of European citizens,” said Philippe Clar, Defense Programs Director at ArianeGroup.


This project will build on ArianeGroup’s ongoing activities through its telescope surveillance network comprising 15 stations worldwide, which today provides services to government, institutional, and private customers. ArianeGroup provides high-precision daytime and nighttime positioning and orbitography data, and analyzes space objects in various orbits. The service is fully geared to the surveillance, tracking and collision warning needs of civil and military satellite operators, allowing them to protect their satellites against all forms of risk.


Eutelsat, as co-contractor, will design, procure, and operate the first satellite in this space segment and supply the data. Eutelsat has therefore partnered with Sodern, which will draw on its experience in the development and production of cameras for SSA applications to design and build the onboard space sensor. “Exo-atmospheric space represents a new challenge for the sovereignty of Europe and the protection of its space infrastructure. Eutelsat intends to play a full role in the global effort to monitor space and understand its environment by leveraging the company’s multi-orbital and multi-mission infrastructure, while joining forces with a leading player in space surveillance,” said Serge Cholley, Defense and Security Director at Eutelsat.


A communications satellite operator for 45 years, French company Eutelsat has built up in-depth expertise in the space environment, protecting its fleet from in-orbit risks. It is this know-how that the company will leverage to serve French and European interests, for the protection of people and property. Today, Eutelsat’s ambition is twofold: become the leading space surveillance operator for the protection of commercial space operations, and be a key player in France’s defense space strategy.


Magellium, also a co-contractor on the project, will develop the image processing for use on different types of optical payloads. Magellium was founded in 2003, based on independent and sovereign expertise in space image processing and its downstream applications. This expertise has been serving space surveillance since 2015, with the development of the space object detection and tracking function of the Tarot telescopes for CNES, followed by a noteworthy participation in the EU SST project on the same function, adapted to onboard processing and completed by a versatile and “high-fidelity” simulator of space observation scenes from both the ground and space. On this ambitious project, Magellium will be implementing its cutting-edge onboard solutions, resulting from its most recent R&D.


The “Data Catalog for Space Surveillance” RFP was launched on April 29, 2022 and was assigned by the French government to CNES as operator of the France 2030 space component. The objective is to significantly improve the security of space operations through data collection.


The consortium was selected in December 2022 from among the five short-listed contenders, with its proposal to develop innovative optical sensors, both on Earth and in space. These sensors will aim to significantly improve the number of objects catalogued in all orbits, as well as their precise orbital location and the regularity of observation, while detecting smaller objects.


The synergies made possible by the combination of new-generation ground-based sensors and satellites equipped with optical sensors will significantly improve the data collected by ArianeGroup’s command and control center. The processing and analysis of this new data will contribute to the development of space surveillance services.


The project will commence with a 24-month pre-operational phase, followed by an 18-month operational service demonstration phase, as decided by CNES.
