卫星星座的演化

Evolvement of Satellite Constellation

本文详细讨论了各种摄动因素的特征以及对MEO的影响，并在文献1的基础上进一步分析了日月引力摄动对星座几何结构演化的影响。由于日月引力摄动的存在，它将导致卫星轨道倾角的变化，从而改变星座中轨道平面的相对位置，引起星座的性能变化。

This article discussed the characteristic of various perturbation factor and the influence on MEO in detail. Based on the literature 1,this article analyzed the influence on the evolution of constellation geometry structure caused by the gravitation perturbation of the sun and the moon. Because of the existence of the gravitation perturbation of the sun and the moon, it will result in the change of the satellite orbit obliquity, change the opposite position of orbit plane in the constellation thus, and bring change to the constellation performance.
