摘　　要：传统成像卫星任务规划过程中任务在时间窗口确定后是不可变的,但受限于卫星的各类约束条件,有些任务无法执行。针对该问题,在任务可以压缩的前提下,提出了采用多种任务压缩的方法处理指令模板冲突和消解文件下传约束,提高规划结果质量。对任务压缩策略进行了实验,测试结果表明,任务压缩策略的使用能够有效优化规划结果,提高卫星观测时长和完成任务数。In the process of traditional imaging satellite mission planning,task is immutable after the confirmation of time window.Owing to the limitation of various satellite constraints,some tasks cannot be completed. To solve this problem,a variety of task compression strategies were proposed to deal with instruction template conflict and to resolve file downstream constraint under the premise that the task can be compressed,in order to improve the quality of planning results.Finally,the task compression strategies are tested.The results indicate that the use of task compression strategies can effectively optimize the planning results and increase satellite observation time and tasks completed.
