摘　　要：基于开普勒第三定律,研究Starlink卫星轨道运行轨迹,分析其轨道运行特征,建立轨道仿真模型,使用高阶的Runge-Kutta方法求解方程,并利用STK对中国东南地区以及中国低纬度地区的Starlink卫星覆盖情况进行分析。仿真结果表明:随着Starlink卫星发射数量的增加,整体覆盖能力稳步提升。最开始1000颗卫星的覆盖范围在北纬54°至南纬54°之间,中国低纬地区的覆盖程度要比中纬地区低;2000颗卫星在此范围之间的覆盖达到了100%,3000颗卫星的覆盖水平明显提高,并且向两极方向延伸,但是一直无法覆盖两极地区。Based on the Kepler's third law of planetary motion,this paper studies the orbit trajectory of Starlink satellite,analyzes its orbit characteristics,establishes an orbit simulation model,uses the high-order Runge-Kutta method to solve the equation,and uses STK(Satellite Tool Kit)to analyze the coverage situation of Starlink satellite in southeast China and lowlatitude areas of China.The simulation results show that the overall coverage capacity is steadily improved with the increase in the number of Starlink satellite launches.The coverage of the first 1000 satellites is between 54°N and 54°S,and the coverage degree of low-latitude areas in China is lower than that of the mid-latitude areas.The coverage of 2000 satellites has reached 100%between this range,and the coverage level of 3000 satellites has increased significantly,and it has extended to the poles,but it has not been able to cover the polar regions.
