The Essaim demonstrator was a system of several micro-satellites (Essaim means 'swarm' in French) for 'analysis of the electro-magnetic environment of the Earth's surface' (electronic intelligence). DGA, the French Ministry of Defence's procurement agency, developed the project. The system also comprised a ground control segment and a ground station for data processing. It was called a 'demonstrator' since the mission's objective was to assess the operational capability of such a system, paving the way for the next generation. The Essaim satellites were based on EADS Astrium's Myriade multipurpose micro-satellite. In early 2000, the DGA awarded the contract for the development, manufacturing of this turnkey system of micro-satellites and associated ground segment. Under the contract, EADS Astrium was also responsible for personnel training and system operations during the three-year life duration of the programme.
