摘　　要：卫星数传调度问题是一类复杂的组合优化问题,即如何为卫星数传任务分配地面资源的问题,它是当前航天领域需要重点研究的问题之一。STK/Scheduler模块是STK工具包中的调度模块,对外提供了二次开发功能。针对卫星数传调度问题,研究了STK/Scheduler模块在该问题中的应用。首先在分析问题的基础上建立了卫星数传任务模型和调度模型,然后对基于STK/Scheduler的卫星数传调度系统进行了设计。最后利用AFIT基准数据进行了验证,结果表明在卫星数传任务规模不太大的情况下,STK/Scheduler为卫星数传调度问题的求解提供了一条捷径。Satellite data transmission scheduling is a kind of complex combinational optimization problem, which means how to assign ground resources for satellite data transmission tasks, and is one of the important problems in space flight. The module of STK/Scheduler is a scheduling module of STK and offers the function of re - exploitation. This paper studies the application of STK/Scheduler in satellite data transmission scheduling. At first, based on the analysis of this problem, satellite data transmission task model and scheduling model are established. Then, satellite data transmission scheduling system based on STK/Scheduler is designed. At last, by using AFIT benchmark, the scheduling result shows that when the task scale is not very larger, STK/Scheduler is a shortcut for the problem of satellite data transmission scheduling.
