Abstract: According to the principle of traditional east-west station-keeping, we develop a new strategy of east-west station-keeping using fixedperiod continuous impulsive maneuver for geostationary satellite in this paper. Based on the analysis of perturbation, the control flow and the control parameters are designed. The effects on orbit parameters, attitude control and angular momentum management are analyzed. Evolutions of semi-major axis, eccentricity and mean longitude for one year are simulated by a realistic example. Simulation results indicate that the satellite’s mean longitude is kept in tolerance window for a long time. The new strategy has the advantage in its simpleness of control flow and in its accuracy of station keeping.

Key words: fixed-period continuous impulsive maneuver, east-west station-keeping, control strategy
