境内建站全球通信条件下的宽带LEO星座卫星通信系统组网方法研究
|
摘要
分析"天星地网"与"天基组网"两种常用的组网方式应用于我国的宽带LEO星座卫星组网方式的可用性,结果证明两种组网方式应用于我国的宽带LEO星座卫星通信系统都有很大的不足;提出一种基于卫星透明转发与处理转发相结合的天地混合组网的方式,这种组网方式更适合在境内建站全球通信条件下建设我国的宽带LEO星座卫星通信系统,宽带LEO星座卫星通信系统与其他卫星通信系统最大的不同是系统要求的传输速率较高;还将重点研究不同组网方式下的系统传输容量。
This paper analyzes the usability of two kinds of commonly used networking methods, "Star-Ground Network" and "Space-Based Networking", for broadband LEO constellation satellite networking in China, The analysis results show that the two kinds of networking methods have great shortcomings when applied to the broadband LEO constellation satellite communication system in China, then a hybrid network based on satellite transparent forwarding and processing forwarding is proposed,The broadband LEO constellation satellite communication system is different from other satellite communication systems in that the transmission rate required by the system is higher. Therefore, this paper will focus on the study of the transmission capacity of the system under different networking modes.
