Optimal Scheduling of Ground Station Network Resources in Satellite-Ground Systems:Overview and Prospects

随着航天科技的发展,太空中的卫星数量大幅上升,与此同时星地系统中的卫星任务调度需求也显著增加。因此,这不但增加了利用有限地面站网资源完成卫星任务的难度,也对星地系统站网资源优化提出了更高的要求。本研究关注星地系统中的站网资源优化调度问题。首先,梳理了地面站网资源调度的发展历程及其研究现状;接着,分析了地面站网资源调度常见的优化目标与约束条件;随后,整理了地面站网资源优化调度的求解算法并总结算法的特点及适用场景,最后对地面站网资源调度的未来研究方向进行了展望。

With the development of space technology,the number of satellites in space has risen dramatically,and the satellite mission scheduling demand in the satellite-ground system has also increased significantly,which increases the difficulty of completing the satellite mission with the limited ground station network resources,and also puts forward higher requirements for resource optimization.This paper focuses on the research of optimized scheduling of ground station network resources in the satellite-ground system.Firstly,this paper sorting out the development history of the ground station resource scheduling problem and its current research status;then,it analyzes the common optimization objectivesand constraints of this problem;then,it introduces the algorithms for solving this problem and sums up the characteristics of the algorithms and the applicable scenarios,and finally,it looks forward to the future research direction of the ground station network resource scheduling problem.
