摘要
近年来随着人类太空探索的快速发展,大量低轨星座相继部署,以星链为代表的星座已掀起了各国的研究热潮。该综述旨在结合低轨星座网络拓扑特点,对抗毁性评估指标和优化模型进行总结剖析。以星链为例,阐述了新型低轨星座的建设现状,对常见的卫星网络拓扑构型进行了分类与优劣对比,分别从节点和链路两个角度梳理了近年来的建模方法。比较评价了典型的抗毁性评估测度与方法,总结了卫星网络拓扑优化算法的研究现状及存在问题,从应用层面提出展望。
In recent years, with the rapid development of human space exploration, a large number of new low-orbit constellations have been deployed one after another. The satellite constellation represented by Starlink has set off a research upsurge in various countries. This review aims to summarize and analyze the destructive evaluation index and optimization model based on the topology characteristics of the low-orbit constellation network. Firstly, taking Starlink as an example,the construction status of the new low-orbit constellation is described, and the common satellite network topologies are classified and compared. From the perspectives of nodes and links, the modeling in recent years is reviewed respectively.Then, the typical survivability evaluation measures and methods are compared and evaluated. At the same time, the research status and existing problems of the satellite network topology optimization algorithm are summarized. Finally, the prospect is put forward from the application level.
