临近空间光传输网络结构设计

Design of optical transport network architecture in near space

利用高性能激光链路互联临近空间平台,组建临近空间平台光网络,向上可与卫星互联,向下可与地面站互联,能够实现高速、大容量及远程数据中继。从构建临近空间光传输网络结构出发,首先根据平台之间连接方式的不同,列举出四种可能存在的HAP网络拓扑结构;然后从云层高度、大气效应、微波接入需求和临近空间环境四个方面总结了影响HAP网络结构设计的因素;最后参考以上分析结果,对波长资源受限的多平台网络拓扑进行分析。

From the view point of optical transport network in near space,firstly,according to different connection ways between high altitude platforms,four kinds of network topology were listed;then,the factor of HAP network structure design was summarized from four aspects.such as： cloud height,demands of microwave access,atmosphere effect,near space environment;finally,on the basis of these above results,multi-platforms network topology which was limited by wavelength resource was researched.
