摘　　要：目前,低轨卫星星座已成为全球卫星通信的主要手段。其中,最具代表性的是SpaceX公司的"星链"低轨卫星星座,其发展势头迅猛,计划建设一个全球覆盖、高速度、大容量和低时延的天基全球通信系统,提供面向全球的高速宽带接入服务。文中梳理了"星链"星座的空间段和地面段的构成情况,总结了该星座可能产生的影响,并对其未来的应用前景进行了预测。At present,LEO satellite constellation has become the main means of global satellite communication. Among these efforts is the Starlink satellite constellation. Starlink is a satellite constellation designed by the US Company SpaceX. It’s planned to build a space-based global communication system with global coverage,high speed,large capacity and low delay to provide global high-speed broadband access services. This paper combs the composition of the space segment and ground segment of the Starlink,summarizes the possible impact of the constellation,and forecasts its future application prospect.
