针对运行在中高轨道上的全球Walker星座的构形长期保持控制问题,通过分析星座卫星的轨道摄动及构形相对漂移,研究了星座构形长期保持的控制方法及控制策略.对于星座构形的保持,研究了星座构形摄动补偿法,提出了星座构形数值微分修正法.最后给出了全球星座构形长期保持控制策略并进行了仿真验证,仿真分析表明,星座构形数值微分修正法比构形摄动补偿法具有更高的控制计算精度.
Aiming at the long-term control of the global Walker constellation in high orbit, the control method and control strategy for the long-term constellation configuration are studied by analyzing the orbital perturbation and the relative drift of the constellation satellite. For the constellation configuration The constellation configuration perturbation compensation method is studied and the constellation configuration numerical differential correction method is proposed.Finally, the global constellation configuration long-term retention control strategy is given and verified by simulation. The simulation results show that the constellation configuration numerical differentiation Correction method than the configuration perturbation compensation method has a higher control accuracy.
