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。
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.
