摘　　要：在概述非同步轨道卫星通信的基础上,讨论了低轨和中轨(非同步轨道)卫星通信系统的一些基本分析方法和设计思路,如范艾伦(Van Allan)辐射带及其对卫星高度选择的影响,非同步轨道/星座几何学,热噪声、衰落、干扰环境下的系统性能分析方法,对网络拓扑、智能网设计、调制处理、多址连接及通信协议的考虑等.Based on the brief introduction of non-geostationary orbit satellite communications systems, some basic analyzing approaches and designing ideas for LEO and MEO (non-geostationary orbit) satellite communications systems are discussed, including Van Allan rediation belts and its influence on the height selection of satellites, non-geostationary orbit/constellation geometry, analyzing methods of system performance in presence of interference, thermal noise and fading, and considerations to network topology, design of intelligent networks, modulation processing, multiple access and communications protocols, etc.
