The two IDEE (Instrument for the Detection of high-Energy Electrons) sensors designed to measure high-energy electron fluxes from terrestrial gamma-ray flashes (TGFs) in the atmosphere were delivered to CNES’s integration teams on 1 September. The sensors were developed by the IRAP astrophysics and planetology research institute.
Then, on 7 September, the two MEXIC (MultiEXperiment Interface Controller) units were delivered. These units will manage the Taranis payload. Supplied by prime contractor LPC2E, the environmental and space physics and chemistry laboratory, the units contain all the electronics interfacing with the platform, power distribution and data processing circuit boards. The science laboratories working on the mission helped to build these boards, some of which were developed by CNES.
