基于虚拟同轨网络的星间组网通信系统设计
A design of inter-satellite networking communication system based on virtual same orbit network
摘要
Abstract
Aiming at the applied background of low-orbit Walker constellation,a complete satellite network communication system architecture based on a hierarchical clustering routing protocol is proposed,which covers the network layer,data link layer and physical layer.For ease of analysis,a typical model of low-orbit Walker constellation is built firstly.The topological characteristics and the communication visibility between satellites with different orbital phase factors and orbit inclination are analyzed.Then a concept called Virtual Same Orbit is proposed in the paper based on the constellation topology,and a double layer network is built according to the Virtual Same Orbit.Finally,for this double-layer network,the specific schemes are given in the network layer,data link layer and physical layer respectively to achieve information interaction between same-orbit and different-orbit satellites.The communication protocol stack designed in this paper considers the cross-orbit information transmission scheduling problem of Walker constellation,taking into account the transmission efficiency and design complexity,which has certain reference value for the design of other Walker constellation inter-satellite networking systems with similar configurations.关键词
