摘　　要：研究了在地面站资源有限、数传任务急剧增多的情况下,合理分配资源以有效实现卫星数传任务的调度问题.首先建立了卫星数传任务模型和调度问题模型,提出了综合优先度的概念及其各个指标,对每个指标进行了详细分析.在此基础上,提出了一种基于综合优先度的卫星数传调度算法。仿真结果表明该算法能够取得较好的调度结果.This paper studies the scheduling problem of satellite data transmission, which is how to assign ground station resources reasonably in order to accomplish satellite data transmission tasks scheduling effectively on the condition of many tasks but finite resources. Firstly, the paper establishes satellite data transmission task model and satellite data transmission scheduling model, and then puts forward the composite-priority concept and its component indexes, and analyzes each index in detail. Based above, this paper gives a composite-priority-based satellite data transmission scheduling algorithm. By simulating, it shows that the algorithm can give satisfactory scheduling results.
