摘　　要：利用卫星仿真工具包(STK)建立了Starlink星座覆盖模型,对其在南北纬70°范围内的覆盖能力进行了仿真分析,具体分析了星链星座对华盛顿、北京、中国台湾、基辅四个地点及其所在四个地区的覆盖能力。仿真结果表明,目前,星链星座能够达到对南北纬约60°之间地区的100%覆盖率,1.5版星链卫星开始覆盖两极地区,星链星座向实现全球覆盖方向稳步发展;星链星座对华盛顿、北京以及基辅等高纬度地区能够实现24小时全覆盖,且覆盖重数较大;对中国台湾等低纬度地区还有部分时刻无法实现连续覆盖,但整体覆盖能力正稳步提升。In this paper, the coverage model of Starlink constellation is established by means of the Satellite Simulation Kit(STK), and the coverage capability of Starlink constellation to Washington, Beijing, Taiwan and Kiev, which are located in north latitude 70 degree to south latitude 70 degree, is simulated and analyzed in detail. The simulation results show that the Starlink constellation can reach 100% coverage between the north latitude about 53 degree to south latitude about 53 degree, and the 1.5v Starlink satellites begin to cover the bipolar areas up to the present. Obviously, the Starlink constellation is developing steadily towards global coverage. According to simulation results, the Starlink constellation can achieve 24-hour full coverage in high latitudes such as Washington, Beijing and Kiev, and the coverage satellites number is large. But the Starlink constellation can’t achieve 24-hour full coverage in Taiwan and other low latitude regions. In conclusion, the Starlink constellation coverage capacity of all regions in the world is improving steadily and in high speed.
