摘　　要：首先对星链星座发展现状进行概述;然后从系统组成、卫星迭代版本、星座构型以及系统发展特点等方面对星链系统进行研究;最后通过仿真对基于星链星座和地面光纤的端到端传输时延进行对比,得出端到端基于不同传输路径的传输距离与时延的关系。通过链路估算,从传输速率方面评估星链卫星对不同业务的服务水平,并从单星覆盖、星座覆盖以及用户可见性方面对覆盖能力进行分析。This paper first provided an overview of the current status of the Starlink constellation development,then studied the Starlink system from aspects such as system composition,satellite iteration versions,constellation configuration,and system development char‐acteristics.Finally,through simulation,a comparison of end-to-end transmission latency based on the Starlink constellation and terres‐trial fiber optics was made,and the the relationship between the end-to-end transmission distance and the delay under different transmis‐sion paths was obtained.Moreover,through link estimation,the service level of Starlink satellites for different services could be evalu‐ated from the perspective of transmission rate.Further,an analysis of the coverage capabilities of a single satellite and the constellation was conducted.

关 键 词：星链星座 系统组成 传输时延 传输速率 覆盖能力
