文摘This paper has analyzed the perturbations of a GeoX-Sat （virtual satellite） in geostationary orbit （GEO）. And control methods, strategies and calculation processes are designed of the East-West （E/W） station-keeping of the GeoX-Sat. The Attitude and Orbit Control Subsystem （AOCS） provides attitude information and maintains the required spacecraft attitude during all phases of the mission, starting at spacecraft separation from the launch vehicle and throughout its operational lifetime. For the GeoX-Sat exercising design, due to time limitations; only two modes of operation were considered after assumed launching operation： normal and station keeping.
