Timeline

 
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.
