摘　　要：针对中继卫星任务规划问题开展研究,提出一种基于执行时段滑动调整策略的任务规划算法。首先分析了中继卫星资源调度过程,并对任务申请的时间特征进行形式化描述,然后归纳出任务分配的主要约束,从而完成问题建模。在此基础上,对优化算法进行设计,给出了执行时段滑动调整步骤。通过调整已规划任务执行时段的方法,使部分原本无法执行任务具备执行可能,提升了任务执行率和资源利用率。在仿真实验中,通过大规模测试分析对比不同算法的优化效果,验证了文中所提方法的有效性。A mission programming algorithm based on execution time slide adjustment strategy is proposed for TDRS（Tracking and Data Relay Satellite）satellites.The following analysis of TDRS resource scheduling process and formalized description of the time characteristics of mission applications,the main constraints of mission allocations are summarized and a TDRS scheduling model is developed.Based on this,an optimization algorithm is designed and execution time slide adjustment steps are given.Using the method to adjust the execution time of programmed missions,it is now possible to execute the missions previously impossible and the mission execution ratio and resource utilization ratio are increased.The effectiveness of the proposed method is validated by the comparisons between the optimization results of different algorithms through series of tests and analysis during simulation tests.
