| 摘 要： | 通过研究当前GPS下时分多址（TDMA）体制星间链路方案，并在分析星间链路测量和通信新需求的基础上，提出改进的分时体制星间链路方案，保证了测距和通信的同时隙执行。针对兼顾星间测量和通信的星间链路设计这一多目标优化问题，考虑测量与通信之间的依赖关系，构建双层规划模型求解，上层对星间测量进行优化，下层对星间通信进行优化，并分别设计上层启发式星间测量链路贪婪搜索分配算法（RL-HGSA）和下层基于全局“邻域”搜索的星间路由优化算法(ROA-SGN)。仿真算例表明，根据本文模型和算法构建的星间链路，星间测量链路利用率达到100%，星间通信采用最短时间最少跳数(MTMJ)的路由策略更优。

| Abstract: | An improved inter-satellite link scheme is designed which ensures to execute inter-satellite ranging and communication at the same time-slot, based on the study of scheme of inter-satellite links on GPS time division multiple access(TDMA) basis and the analysis of the new requirements of inter-satellite ranging and communication. Considering the inter-satellite link designing of giving consideration to both ranging and communication is a multi-objective optimization problem and the dependence of ranging and communication, a bilevel programming model is put forward, in which the top level optimizes the inter-satellite ranging and the next level optimizes the inter-satellite communication. A ranging link heuristic greedy searching algorithm (RL-HGSA) and an inter-satellite routing optimization algorithm based on searching the global neighborhood (ROA-SGN) are designed. A simulation example is designed to validate the model and algorithm. The result shows the use ratio of ranging links can reach 100% and the minimum time and minimum jump (MTMJ) route strategy is better in communication. |
