DEMETER

DEMETER [CNES]

DEMETER (Detection of Electro-Magnetic Emissions Transmitted from Earthquake Regions) is the first project in the CNES Myriade microsatellite series. The scientific purpose of the mission is to:

  • study the ionospheric disturbances related to seismic activity,
  • study the ionospheric disturbances related to human activity,
  • study the pre- and post-seismic effects in the ionosphere,
  • contribute to understand the mechanisms generating those disturbances,
  • give global information on the Earth's electromagnetic environment at the satellite altitude.

The scientific component 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.
