考虑J_2项摄动的卫星编队飞行

Satellite Formation Flying with J_2 Perturbation

针对参考卫星运行于圆轨道的编队飞行 ,分析了J2 项摄动的影响。在此基础上提出了一种方法 ,通过调整环绕卫星的半长轴 ,大大减小了J2 项摄动对编队飞行的破坏作用。此外 ,基于冲量假设估计了编队保持的代价。数值结果表明 ,调整长半轴的卫星编队可以长期保持 ,节省了大量的控制燃料。

As to the formation flying with the reference satellite running on the circle orbit, the J 2 effect is analyzed. On this basis, a method is presented, which can greatly mitigate the breakage of the J 2 term by adjusting the semi major axis of the flying around satellite. Furthermore,the cost required for formation keeping is evaluated under impulse assumption. Numerical results show that satellite formations with semi major axis adjustments will last much longer, and save much more fuel.
