摘要： 针对低轨大规模星座卫星间碰撞安全问题，对星座构型的最大漂移量开展了研究。基于球面三角形理论计算了卫星轨道平面的最小相位差；采用控制变量法对星座构型参数进行研究，分析不同构型参数对星座卫星最小相位差的影响，以及升交点赤经漂移量与最小相位差的关系，提出了基于最小相位差的星座构型参数协同设计方法；基于相对相位分析方法，建立升交点赤经漂移量与相位漂移量随时间变化的函数关系；最后，以Starlink第一期星座为参考对象进行仿真，验证了构型参数协同设计方法的合理性。

Abstract: Aiming at the collision safety of large-scale constellation satellites in low Earth orbit（LEO），the maximum drift of constellation configuration was studied.Firstly，the minimum phase difference of satellite orbit plane was calculated based on the spherical triangle theory.Secondly，the constellation configuration parameters were studied by using the control variable method.The influence of configuration parameters on the minimum phase difference of constellation satellites was analyzed，and the relationship between the right ascension drift and the minimum phase difference was analyzed.A cooperative design method of constellation configuration parameters based on the minimum phase difference was proposed.Then，based on the relative phase analysis method，the function relationship between the right ascension drift and the phase drift with time was established.Finally，the first phase of Starlink constellation was taken as a reference object to verify the rationality of the collaborative design method of configuration parameters.
