CNES oversaw the Demeter system’s development and was prime contractor for the Technological Mission Centre (CM-T).
The LPC2E (former LPCE) was prime contractor for the scientific payload’s development, as well as for the mission’s Scientific Mission Centre. It was also in charge of developing the BANT electronic module and the IMSC instrument.
Other French laboratories also took part in the Demeter mission: IRAP (former CESR) developed the IDP instrument, the LPP (former CETP) developed the IAP and ICE instruments, the Nançay observatory worked on the BANT module’s analogic aspects, the IPGP supplied seismic data; the LDG/CEA and IDF Sophia labs, as well as LESIA, also took part in the mission.
The OPGC carried out ground experiments during the Demeter mission to measure electromagnetic fields in selected areas, such as the Corinthian Gulf or the Piton de la Fournaise volcano on Réunion Island. The results were compared to those obtained at the same time by the satellite, in order to understand the physical processes behind these emissions.
In Europe, ESA developed the ISL instrument via ESTEC. the Polish Space Research Centre (CBK) contributed to the BANT’s DC/DC module and the payload test bed.
Data was processed in the Scientific Mission Centre in Orléans, France. Japan’s University of Electro-Communications also contributed to processing scientific data.
