摘要:  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.

Abstract: Abstract:Aiming at orbital maintenance of the Walker constellation configuration in medium earth orbit considering the effects of orbital perturbation, we discuss the excursion of the constellation configuration. After this, the long-time maintenance control methods and the control strategy of the constellation configuration are discussed. The perturbation penalty method has been analyzed. The numerical differential modified method of the constellation configuration is presented and discussed. Finally, the long-time orbital control strategy for global constellation is presented and simulated. Simulation analysis shows that the constellation configuration numerical differential modified method can achieve higher control calculation accuracy than constellation configuration perturbation penalty method.

Key words: satellite constellation, Walker constellation, constellation control, orbital control
