DEMETER is a French micro-satellite operated by CNES devoted to the investigation of the ionospheric disturbances due to seismic and volcanic activity. It was launched on June 29, 2004.
Demeter stands for Detection of Electro-Magnetic Emissions Transmitted from Earthquake Regions. The CSRC was responsible for the interface system for Langmuir probe – intelligent interface between the Langmuir probe and a ground system for scientific data acquisition. The interface board operation was designed to be controlled by the software application with graphical user interface. The project was done in cooperation with the IAS CAS Prague.
