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.

Demeter - . Mass: 125 kg (275 lb). Nation: France. Agency: CNES. Class: Earth. Type: Seismology satellite. Spacecraft Bus: Myriade. Spacecraft: Demeter. USAF Sat Cat: 28368 . COSPAR: 2004-025C. Apogee: 723 km (449 mi). Perigee: 695 km (431 mi). Inclination: 98.30 deg. Period: 99.00 min.
Demeter studied disturbances of the ionosphere due to seismo electromagnetic effects and human activities (power lines, VLF transmitters, HF broadcasting stations). Study of natural electromagnetic emissions in the ULF/ELF/VLF range related to seismic or volcanic activity could be used to predict earthquatkes or eruptions in advance. Demeter tracked these emissions and other space plasma parameters (ion composition, electron density and temperature, energetic particles). The scientific payload consisted of three electric and three magnetic sensors (covering six components of the electromagnetic field from DC to 3.5 MHz); a Langmuir probe; an ion spectrometer; and an energetic particle analyzer. 8 Gbits of onboard memory recorded the data, which was returned to earth as 18 Mb/s high bit rate telemetry in the X band. The two-year mission was handled from a control center in Toulouse.

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.

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.
