摘　　要：针对偏置动量卫星的特点,提出了一种偏置动量卫星东西位置保持策略优化方法。根据单自由度轮控系统的控制方式、角动量管理的控制方法,以及角动量管理对卫星轨道的影响,基于动量轮转速的变化建立了推力器喷气效率、轨道元素变化量计算模型,提出了可延长东西位置保持周期的轨道控制优化策略。实际轨控任务应用结果表明方法控制效果良好。According to the characteristics of biased momentum satellite,the optimum strategy of east-west station-keeping was put forward in this paper.The control mode of single gimbaled wheel attitude control system and long-term momentum management was studied.The influence of long-term momentum management on satellite orbit was analyzed.The calculation model of engines＇efficiency and orbit change was derived based the variation of momentum wheel rotation rate.The optimum strategy of east-west station-keeping was presented which would prolong station-keeping cycle.The result of the real orbit control task showed that the strategy was good.
