摘要
本文在介绍星间链路空间几何参数模型的基础上,从网络的角度研究了卫星星座网络的拓扑变化规律,主要是星间链路变化规律,分析了不同类型的星座模型对星间链路变化的影响。最后,结合卫星网络中的路由分析了这些变化对路由计算周期的影响。
Building networks with inter-satellite links （ISL） in the MEO/LEO satellite constellation is becoming a major trend of broadband satellite network. In order to perform routing in a satellite network, the dynamic characteristics of network topology must be considered because of the ISL＇s changes caused by the continuous movement of satellites. By introducing the geometric parameters of ISL, the characteristics of network topology, especially of ISL, are studied in this paper from the viewpoint of network. The influence on the changes of the ISL of different constellations is analyzed. Finally we analyse the influence of the changes on the routing computation period by considering the routing in the satellite network.
