摘　　要：参考地球静止轨道卫星传统东西位置保持控制原理,提出连续式等间隔脉冲推力东西位置保持策略.在摄动分析基础上,给出该策略的控制流程以及控制参数计算公式,进行了轨道参数、姿态控制和角动量管理三方面的影响分析,仿真验证了该策略作用下卫星半长轴、偏心率和平经度的变化趋势,结果表明新策略可以长期有效地控制卫星平经度在漂移环范围内,并具有控制流程简单,位保精度高等优势.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.
