Station-keeping control method for GEO satellite based on relative orbit dynamics

Based on the analysis of relative orbit dynamics for GEO (geostationary orbit, GEO) satellite and LQG (Linear Quadratic Gaussian, LQG) algorithm, this paper proposed a station-keeping control method for GEO satellite, which realized north-south station-keeping and west-east station-keeping simultaneously. To further verify the effectiveness of the proposed method, corresponding mathematical simulation is carried out. Simulation results show that the proposed method can obtain good control precision compared with conventional station-keeping control method of GEO satellite. Thus, the proposed method is suitable for station-keeping control of GEO satellite.
