摘　　要：利用Starlink星座公开的轨道数据,对2021年初入轨的极轨激光试验卫星和当年9月开始的业务激光星座部署的完成情况、轨道构型设计、星座维持控制策略和激光通信跟踪参数等进行了分析和计算,极轨激光试验卫星进行了2个阶段的近、远距离的激光通信试验,业务星座中的880颗卫星已经完成了网络的基本构型,具备了使用激光终端进行业务组网的条件,同时,这些采用电推进控制系统的卫星轨道控制频繁、相位保持精度高,分析和计算结果与轨道维持策略对后续建设大规模星间链路的星座具有很强的参考价值。Using publicly available orbit data from Starlink constellation,the deployment completion status,the orbit configuration design,the constellation maintenance control strategy,and the laser communication tracking parameters of the polar orbit laser test satellite that entered orbit in early 2021 and the operational laser satellite constellation that began in September of that year are analyzed and calculated.The polar laser test satellite has carried out two stages of near and long distance laser communication tests,880 satellites in the service constellation have completed the basic configuration of the network and are qualified to use laser terminals for service networking.At the same time,these satellites using the electric propulsion control system feature frequent orbit control and high phase keeping accuracy.The analysis and calculation results and orbit maintenance strategies have a strong reference value for the subsequent construction of large-scale inter-satellite link constellations.
