Satellite
The Demeter satellite comprised:
- The micro-satellite platform with basic instruments. This bus was designed for satellites with a launch mass of about 100 kg. Its attitude control systems included a star tracker, gyrometers, and reaction wheels. It used hydrazine for station keeping. Centralised on-board management was built around a 10 MIPS T805 processor. A mass storage module was available for data storage. Telemetry and remote controls used the CCSDS standard.
- The payload, comprising technological elements and scientific elements:
- Technological elements:
- an 8 Gb mass storage unit,
- high-speed telemetry (THD),
- the COA-GPS experiment (GPS Autonomous Orbit Control),
- the pyrotechnical system photonic initiation line (PYROLASER),
- the thermal control coating qualification (THERME).
- Scientific elements:
- IMSC, a tri-axis set of 3 magnetic sensors (search coils),
- ICE, a set of 4 electric sensors,
- IAP, a plasma analyser,
- ISL, a Langmuir probe,
- IDP: a particle detector.
- Technological elements:
Demeter was launched from Baikonur cosmodrome, using a DNEPR launcher carrying other passengers.
