摘要
SpaceX公司的Starlink系统是目前设计规模最大、发展最快的卫星网络系统,系统建成后,将能向民用和军用领域提供全球范围的高速宽带网络服务。介绍了该系统的轨道信息、工作频率、波束覆盖、星座协同、用户终端与网关地球站及抗干扰策略,从中可以看出其系统的技术先进性,也为今后对Starlink系统的进一步研究打下基础。
Starlink system of SpaceX is the largest design scale and fastest growing satellite network system currently.When the system is built,it will be able to provide global high-speed broadband network services to ci⁃vilian and military fields.The system's orbit information,working frequency,beam coverage,constellation coor⁃dination,user terminal and gateway earth station,and anti-jamming strategies are introduced.It shows that the system is technologically advanced and will lay the foundation for further research in the future.
