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 characteristics. Finally
through simulation
a comparison of end-to-end transmission latency based on the Starlink constellation and terrestrial fiber optics was made
and the the relationship between the end-to-end transmission distance and the delay under different transmission paths was obtained. Moreover
through link estimation
the service level of Starlink satellites for different services could be evaluated from the perspective of transmission rate. Further
an analysis of the coverage capabilities of a single satellite and the constellation was conducted.
