| 摘 要： | 设计了一种新型的LEO/MEO全球覆盖双层卫星光网络,该结构具有稳定的MESH型连接关系,不仅满足卫星光通信捕获追踪和瞄准ATP(acquisition tracking and pointing)要求,还能简化星载处理和交换,降低路由开销。推导了同层和异层间星间链路空间位置表达式。数值仿真结果表明该网络相邻卫星间距离、方位角和俯仰角变化范围小,非常适合卫星激光链路,可作为构建未来卫星激光网络的参考。

| Abstract: | A novel two-layered optical satellite network of LEO/MEO with global coverage is designed,which has the quality of quasi-static connectivity of MESH.It satisfies the demand of ATP(acquisition,tracking and pointing)in optical satellite communication and simplifies processing,switching on board satellite,reducing routing overhead.Spacing position expressions of inter-satellite links between the same and different layers are deduced.Simulation results show ranges of distance,azimuth and elevation between two n... |
