摘要

当前，陆地通信系统已无法满足日益复杂的信息需求，利用空间信息网络实现全球范围内的无缝覆盖和高效容量传输成为研究热点。现有卫星通信系统以单层星座为主，缺少高低轨卫星之间的协同。提出了一种基于分布式星群的双层星座设计，以基于分布式星群的低轨卫星作为网络架构的基础，采用星间链路实现低轨卫星之间的通信，通过高轨卫星实现中低纬度地区覆盖性能加强。仿真结果表明，所提方法在仅依靠在国内部署卫星地面站的前提下可实现全球多重覆盖。

Abstract

Nowadays

the land communication system is unable to support the complex information needs

and realizing global seamless coverage and high capacity through space information network is anticipated.The existing satellite network is mainly composed of single satellite constellation

which absents the cooperation between the low earth orbit (LEO) satellites and geostationary orbit (GEO) satellites.A double-layer satellite constellation based on distributed satellite clusters was proposed

in which the infrastructure layer was composed of LEO satellites

the communication between LEO satellites was accomplished over inter-satellite links (ISL)

and GEO satellites enhance the performance of coverage in low and middle latitudes.As simulation results show

the proposed approach can realize excellent global multiple coverage only relying on the deployment of satellite earth stations in China.
