摘要
MEO卫星通信系统星际链路网络拓扑采用Walker星座设计,每颗卫星采用四链路结构,分别与前后左右的卫星相连。其前后链路属固定链路,处于同轨道面内。物理层则采用接收功率描述。对链路长度和接受功率的变化进行仿真和分析,用于指导天线的设计及其发射功率的控制。
The Walker constellation design was adopted by network topology of ISL network in MEO satellite communication system. Four ISLs structure is used by every Satellite to connect itself with fore-and-aft and right-and-left Satellites. The fore-and-aft ISLs are fixed ISLs and stayed in the same orbit. Physical layer is described by receiving power The changes of linkage length and receiving power were simulated and analyzed to command the aerial design and the launching power control.
