利用相对轨道根数法研究J2摄动对卫星编队飞行的相对轨道构形的影响,并利用高精度的算法进行数值仿真。结果表明:摄动可以使相对轨道构形发生转动与漂移两种变化。摄动引起相对轨道构形变化的形式,取决于参加编队卫星的轨道根数。当主、从星的轨道参数中只有升交点赤径不相同时,摄动对相对轨道构形几乎没有影响;当主、从星偏心率不相同时,摄动将引起相对轨道构形的转动;而当主、从星之间轨道倾角、近地点幅角和近地点时刻各不相同时,摄动将引起相对轨道构形的漂移。
The relative orbital root number method is used to study the influence of J2 perturbation on the relative orbital configuration of satellite formation flight, and the numerical simulation is carried out by using high-precision algorithm. The results show that perturbation can make the relative orbit configuration change both in rotation and in drift. The form of relative orbital changes caused by perturbation depends on the number of orbits participating in the formation of satellites. When the ascending or descending trajectory of the main and the astroid stars are not the same, the perturbation has almost no effect on the relative orbit configuration. When the eccentric eccentricity of the main and the asteroid are different, the perturbation will cause relative orbital rotation. Perturbation of the orbit will cause relative orbital drift when the orbital angles of the main and the subordinate stars are different from each other at the perigee and the perigee.
