针对靶标场等摄影任务受轨道维持影响大的现状,提出基于摄影任务的轨道维持策略。分析了卫星轨道特性和轨道维持对重要摄影任务的影响,提出利用邻轨搭接特性对摄影区域完成两次摄影的方法。通过某靶标场摄影试验,比较分析得到最优摄影方案,验证了本文方法的可行性。同时完善卫星轨道维持策略,作为卫星实施轨道维持的重要参考依据。 In view of the fact that the photography task such as the target field is greatly influenced by the orbit maintenance, the orbit maintenance strategy based on the photography task is proposed. The influence of satellite orbital characteristics and orbital maintenance on important photographic tasks is analyzed. A method of taking two shots in the photographic area by using adjacent track overlap characteristics is proposed. Through a target field photography test, the optimal photogrammetry is obtained through comparative analysis, which proves the feasibility of this method. At the same time, the satellite orbit maintenance strategy should be perfected as an important reference for satellite orbit maintenance.
