Study on Evolution Analysis and Maintenance Technology of Co-location Configuration of Geostationary Satellites

Multi-satellite co-location is the main means of solving the orbital tension of geostationary satellites. The co-location configuration and control strategy have an important impact on space missions in geostationary orbit. In order to achieve the reliable operation of geostationary satellite constellations, it is necessary to analyze the relative motion between satellites, design a feasible configuration scheme and give an effective co-location maintenance strategy. In view of the above problems, this paper establishes the orbital motion model of geostationary satellite orbital motion, and studies the influence of various perturbation forces during satellite flight. The evolution of co-located satellite configuration and the perturbation factors are analyzed through simulation studies. Finally, a north-south, east-west maintenance strategy is presented, and the simulation results demonstrate the effectiveness of the proposed maintenance strategy.
