摘　　要：自研星座网络模拟系统逐渐成为研究星间组网的必要方式,针对传统星座网络模拟系统和星座设计软件耦合度高,导致星座运动数据解析繁琐、拓扑和链路更新时耗较高的问题,提出了可见性矩阵驱动的星座网络模拟系统,研究了面向通信端口的星座动态拓扑模拟方案和基于数据库存储的链路配置方案。实现结果表明,可见性矩阵驱动的星座网络模拟系统具备高效的星座拓扑更改和星间链路更新的能力,为上层组网算法验证等工作提供时效性强的模拟环境。Self-developed constellation network simulation system has gradually become a necessary way to study intersatellite networking.To solve the problems of complicated analysis of constellation motion data and high cost of topology and link update caused by high coupling degree between traditional constellation network simulation system and constellation design software,this paper proposes a constellation network simulation system driven by visibility matrix.A communication port-oriented constellation dynamic topology simulation scheme and a link configuration scheme based on database storage are studied.The results show that the visibility matrix-driven constellation network simulation system can efficiently change constellation topology and update intersatellite link,which provides a time-efficient simulation environment for upper-layer networking algorithm verification and other work.
