以我国空间信息的应用需求为牵引,设计了一种系统管理简单、成本可控的空间光网络系统。该系统利用MEO卫星组成环形骨干光网络,兼顾微波接入功能,实现骨干接入一体化、激光微波混合化的空间信息网络系统,并对系统覆盖能力进行了仿真,同时结合GEO中继系统和LEO卫星系统的特点,提出分步建设思想,最终实现全球信息传输和应用的空间信息网络系统。

In demand for the application of China′s space information, a simple-managing and controllable-cost space optical network was designed. The established circle backbone network based on MEO satellites was equipped with microwave access ability to realize the backbone-access integrated and optical-microwave hybrid space network system. Coverage capacity was also simulated. The implementation scheme by step which was proposed based on the combination of the characteristics of the GEO relay system and the LEO satellite as well will contribute to the space network system for global information transmission and application.
