摘要： 在推力较小时，通信卫星在远地点变轨的弧段很长，从而导致较大的速度损失。文章采用极大值原理，研究了在远地点采用多次变轨的最优变轨过程。给出了推力方向的最优变化规律及中间轨道的最优值，并对计算结果进行了讨论。

Abstract: In the case of low thrust apogee boost for the geostationary satellite,the gravity loss increases due to the long burn arc. Based on the maximum principle,the optimal multiple-burn strategy is studied in this paper. Finally, the results of optimal thrust direction and optimal intermediate orbits are obtained and discussed.
