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),为星载天线跟踪系统设计和LEO/MEO双层卫星网络最优化路由搜索算法提供依据。

关 键 词:层间卫星星际链路  空间参数  卫星移动通信  LEO/MEO双层卫星网络  地球轨道卫星  数学模型

Abstract: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.
Keywords:Geometric parameter Satellite communication Mathematical model Emalation
