The invention discloses a geosynchronous orbit inclination angle keeping method adopting electric propulsion. The method comprises the following steps: determining the minimum working duration and the maximum working duration of electric propulsion every day; determining and judging the generation opportunity of an electric propulsion north-south position protection strategy; calculating an orbit keeping strategy in an orbit control strategy generation opportunity window; and according to the calculated orbit strategy, executing a corresponding on-off instruction of the electric push engine at the orbit argument meeting the corresponding condition. According to the invention, 1-degree initial orbit depolarization can be realized under the condition of not additionally consuming fuel, and meanwhile, the working duration and the working interval of electric propulsion each day can be uniform, so that the energy balance of the whole satellite is facilitated.

    本发明公开了一种采用电推的地球同步轨道倾角保持方法,包括:确定每天电推最小工作时长和最大工作时长;确定并判断电推南北位保策略生成的时机;在轨控策略生成时机窗口内,计算轨道保持策略;根据所计算的轨道策略,在满足相应条件的轨道幅角处执行相应的电推发动机的开关指令。本发明能够在不额外消耗燃料的情况下,实现1°的初始轨道消偏,同时还能使每天电推工作时长和工作间隔均匀,有利于整星能源平衡。
