针对敏捷卫星一次过境时间内的同轨拼幅观测和同轨多点连续观测模式的姿态机动策略问题,提出一种基于时间序有向无圈图的敏捷卫星姿态机动策略算法.该算法首先将区域目标和点目标转化为若干条带目标,然后通过将各个条带的观测时间窗口离散成一系列带有条带信息的时刻点,构造时间序有向无圈图,将敏捷卫星对地观测姿态机动策略问题转换为图论的寻找最优路径问题.仿真算例表明,该算法能够有效解决敏捷卫星同轨拼幅观测和多点连续观测的姿态机动策略问题,获得最大化观测覆盖收益同时机动时间消耗最小的姿态机动方案.
Aiming at the agile satellite attitude maneuver strategy based on the time-directed directed acyclic map, aiming at the problem of attitude maneuver strategy in agile satellite during the same transit orbit and multi-point continuous observation mode, Regional target and point target are transformed into a number of band targets. Then by constructing the time-ordered directed circle graph by separating the observation time window of each band into a series of time-points with band information, The maneuver strategy problem is transformed into the graph theory to find the optimal path problem.The simulation results show that this algorithm can effectively solve the attitude maneuver strategy problem of agile satellite orbit overlap observation and multi-point continuous observation, Time consuming minimal gesture motor program.
