摘要
低地球轨道 /中地球轨道 (LEO/MEO)双层卫星网络是未来卫星移动通信系统重要组成部分 ,而层间卫星星际链路 (ISL)是影响整体双层卫星网络系统性能的重要因素。文章重点分析层间ISL的空间参数几何特性 (包括星间链路长度 ,星间链路指向方位角和仰角 ) 。
The MEO/LEO satellite network is the important part of future mobile satellite communication system. The inter-layer ISL of MEO/LEO satellite network is an essential factor which effects the performance of the satellite network system. This paper describes geometric characters (including range, elevation angle and azimuth angle) of inter-ISL in MEO/LEO satellite network in order to design efficient tracking system of satellite's antenna and the dynamic routing strategy in MEO/LEO satellite network.
