摘要
低轨星座卫星通信系统中由于卫星间的相对运动使整个网络拓扑变化频繁,是一个全动态网络,这给低轨星座的拓扑控制带来了挑战。研究具有同轨及异轨星间链路的24/3/1Walker星座网络,提出了两种异轨动态建链的拓扑控制方案,并对其进行了相应的仿真研究,得出了有价值的结论。
In LEO satellite constellation communication system,the continual movement between satellites makes the network topology change frequently.The satellite network is a totally dynamical network.Considering the 24/3/1 walker satellite constellation that has inter-ISL and intra-ISL,two network topology control strategies based on intra-ISL linkage were suggested and simulated,and some useful results were provided.
