Micro-satellite product line developed jointly by EADS Astrium and the French Space Agency CNES beginning in 1998.

AKA: AstroSat; AstroSat-100; Elisa; Essaim; Parasol; Picard; VNREDSAT. Status: Operational 2004. First Launch: 2004-12-18. Last Launch: 2013-05-07. Number: 15 . Gross mass: 125 kg (275 lb).

The Myriade program was principally designed for scientific, application and technology missions, in response to increasing demand from the scientific community for quicker, cheaper access to space, with the accent on enhanced payload capacity in terms of mass, power, pointing accuracy, telemetry and processing and orbit control propulsion. The program was also envisaged for institutional or export opportunities. The first mission flying this platform was CNES' scientific microsat Demeter, launched in June 2004, followed by the French MoD system for electro-magnetic environment analysis, Essaim.

  • Parasol - . Mass: 125 kg (275 lb). Nation: France. Agency: CNES. Manufacturer: EADS Astrium. Class: Earth. Type: Atmosphere satellite. Spacecraft Bus: Myriade. Spacecraft: Myriade. USAF Sat Cat: 28498 . COSPAR: 2004-049G. Apogee: 673 km (418 mi). Perigee: 659 km (409 mi). Inclination: 98.0780 deg. Period: 97.91 min.

    Parasol carried a wide-field imaging radiometer/polarimeter called POLDER (Polarization and Directionality of the Earth’s Reflectances), designed in partnership with the LOA atmospheric optics laboratory in Lille (CNRS-USTL). POLDER was designed to improve the knowledge of the radiative and microphysical properties of clouds and aerosols by measuring the directionality and polarization of light reflected by the Earth-atmosphere system.

  • Essaim 1 - . Mass: 120 kg (260 lb). Nation: France. Agency: DGA. Manufacturer: EADS Astrium. Class: Surveillance. Type: ELINT. Spacecraft Bus: Myriade. Spacecraft: Myriade. USAF Sat Cat: 28494 . COSPAR: 2004-049C. Apogee: 673 km (418 mi). Perigee: 663 km (411 mi). Inclination: 98.0760 deg. Period: 97.96 min.

    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.
