Thrust Pointing Adjustment of Electric Propulsion System

Abstract The satellite uses an electric propulsion system (EPS) to complete the north-south station-keeping (NSSK) work. Due change of centroid position during whole life period, thrust pointing adjustment is required minimize deviation between vector and centroid, avoid additional interference torque decrease protection efficiency EPS. In this paper, method designed, mathematical model angle established, conformity spacecraft analyzed, ground integration test verification on-orbit are completed. analysis data show that range accuracy EPS can meet requirements NSSK mission.
