关于星座小卫星的编队飞行问题

从轨道力学角度来看星座小卫星编队飞行和星星跟踪中的伴飞，遵循着如下动力学机制：(1)在各小卫星绕地球运动过程中轨道摄动变化的主要特征决定了星-星之间的空间构形，(2)当星星之间相互距离较近时，在退化的限制性三体问题(实为限制性二体问题)中，共线秤动点附近的条件周期运动亦可在一定时间内制约星-星之间的空间构形．将具体阐明这两种动力学机制的原理和相应的星星之间的相对构形，并用仿真计算来证实这两种动力学机制的适用范围，为星座小卫星编队飞行和在伴飞运动过程中进行轨控提供理论依据和具体的轨控条件．

Problem About the Formation Flying of the Constellations' Small Satellites

From the view of orbital dynamics, the formation flying of the constellations' small satellites and the companying flying in the tracking among satellites are abided by the following dynamical mechanism: (1)The main characters of the orbital disturbing change determine the configuration in sky when every small satellite moves around the Earth, (2)When the distance among satellites is near, the qualified periodic moving near colin-ear equilibrium points in the regenerate restricted three-body problem (factually restricted two-body problem) also restrict the structure in sky in no-long time. This paper clarifys the principle of the two dynamical mechanism and corresponding relative structure among satellites which confirms the proper applying ranges of the two mechanisms with simulative computation and provides theory foundation and concrete condition of orbital controlling when the constellations' small satellites flying formationally and companying.
