A station-keeping control method for GEO spacecraft based on autonomous control architecture

Based on the analysis of perturbation force for GEO (geostationary orbit, GEO) spacecraft and the reference of intelligent autonomous control idea from DS1 (Deep Space 1, DS1), this paper presents a station-keeping control method for GEO spacecraft based on autonomous control architecture, which realizes north-south station-keeping and west-east station-keeping simultaneously. To further verify the effectiveness of the proposed method, corresponding autonomous station-keeping control software is designed and ground simulation test is carried out. Simulation results show that the proposed method achieves a better performance in autonomous station-keeping.
