The design of a power conditioning unit for a field emission electric propulsion (FEEP) system is presented, with special emphasis on north-south stationkeeping application. The propulsion system consists of four thruster pairs (two active at a time and two in cold redundancy) each fed by a thruster dedicated power supply module. A central power and control module provides the bus power distribution, performs the operation control of the overall FEEP system, and exchanges orders and information with the attitude and orbit control system and the ground control directly via the on board data handling bus. The development status, the results achieved, and further steps needed toward the flight model are presented.
