Schematics of the EPS system. Once the kill switches are deactivated at deployment, the EPS, COM, and OBC systems are powered. Two watch dog timers have been implemented, one in the OBC SW with a 2 h period and one in the EPS with a 36 h period. Beacons are generated by the OBC and the COM systems separately; the systems take turns in transmitting their beacons.
