摘要
对现有卫星移动通信系统星间链路的分析发现，随着卫星通信系统轨道高度的增加，卫星通信系统星间链路指向的动态调节范围不断扩大，星间链路的相对距离也不断增大，据此进行了对最优化极轨道卫星通信系统星间链路的主要参数的模拟与分析，并得到了一些规律性的结论，为星间链路的设计与建立奠定了理论基础。同时，卫星通信系统星间链路指向性的周期性规律变化也为星间链路连接过程中最优化搜索算法的建立提供了探索方向和理论依据。
Through the analysis of present mobile satellite communication systems, it is found that the higher the constellation height is, the larger the dynamic range of ISLs direction and the relative distance between neighbour satellites are. From the phenomena, some regular conclusions are drawn by simulating the optimizing polar orbit satellite communication system. They are the indispensable theoretic foundation for ISL design. And the periodic changes of ISL direction provide the direction of investigation and the theoretic basis for the optimizing searching algorithm in the process establishing of ISL.
