CSES (China Seismo-Electromagnetic Satellite)is a scientific mission dedicated: to monitoring electromagnetic field and waves, plasma and particles perturbations of the atmosphere, ionosphere and magnetosphere induced by natural sources and anthropocentric emitters; and to study their correlations with the occurrence of seismic events. The satellite mission is part of a collaboration program between the China National Space Administration (CNSA) and the Italian Space Agency (ASI), and developed by China Earthquake Administration (CEA) and Italian National Institute for Nuclear Physics (INFN), together with several Chinese and Italian Universities and research Institutes. In the CSES project, Innodesi took care of the development and production (up to the Flight model) of the Power Control block of the HEPD sensor (currently operating on CSES-1). Innodesi has also developed the Electrical Ground support equipment (EGSE), the support equipment used to provide background services and operational support to CSES satellites. Finally, Innodesi with INFN researcher have developed two different engineering model of the Electric Field Detector (EFD), able to measure the variation of the ionosphere electric field due to perturbations from solar, seismic and anthropic phenomena and currently under analysis in the INAF and INFN laboratories of Roma Tor Vergata.
