About
TPPRE sits between the satellite’s onboard computer and propulsion actuators — the Xenon Pressure Regulator Unit and Thruster Pointing Mechanisms — performing closed-loop control of Xenon valve actuation and thruster positioning for attitude and orbit control. Each module integrates a power converter board and control board, built with hot/cold redundancy and analyzed with a double-failure-tolerant approach for deep-space and sample-return missions.
