The satellite is composed of:
 

a micro-satellite platform with common equipment.
This platform was designed for about 100 kg mass satellites. Its position control uses a star sensor, some gyrometers and reaction wheels. The orbit control will be done by an hydrazine system.
The on-board management centralised, build using a 10 MIPS micro processor T805. A mass memory is available for the data storage. The telemetries and the telecommande use CCSDS standard.

a payload which is formed by:

    a technological component which includes:
      a 8 Gb mass memory
      a high rate telemetry
      theAOC-GPS experiment (Autonomous Orbit Control by GPS)
      a photonic setting off for a pyrotechnical system (PYROLASER)
      the thermic control coating qualifying (THERME)
    a scientific component which includes the following sensors:
      IMSC: a triaxial set of 3 magnetic sensors (Search Coil),
      ICE: a 4 electrical sensor system,
      IAP: a plasma analyser,
      ISL: a Langmuir probe
      IDP: a particle detector.

DNEPR LauncherThe Launcher that will be used is a DNEPR which would be launched from Baikonour with other passengers.
