| 摘 要： | 针对单层卫星网络功能单一、可靠性较低以及三重卫星网络链路冗余度过高、实现复杂的问题,提出了利用LEO/MEO卫星构建双层网络的构想.基于"最坏观察点"与"覆盖带"理论设计了"弱连接"的LEO/MEO双层卫星网络星座,给出了星际链路建立原则.仿真结果表明,所设计的卫星网络具有全天时全球覆盖能力,有利于星际链路的建立.

| Abstract: | Aiming at the issue of simplex function and low reliability in monolayer satellite network and high ISL complexity in three-layered satellite network,a framework of LEO/MEO network is proposed.Based on the worst observational point and street of coverage theory,a discontinuous connection LEO/MEO constellation is designed,and the principle to establish ISL is put forward.Furthermore,experimental results show that the network has the ability of global coverage and is easy to establish ISL. |
