The invention relates to the technical field of aerospace dynamics and constellation configuration design, in particular to a gravitational wave detection configuration design method utilizing an earth-moon long-distance retrograde orbit, and the method comprises the steps: determining a periodic orbit stability theory according to a kinetic equation of a circular restrictive three-body model; establishing differential correction of a long-distance retrograde orbit in the circular restrictive three-body model, and analyzing the characteristics of the long-distance retrograde orbit by using the differential correction and a periodic orbit stability theory; and gravitational wave detection configurations utilizing the earth-moon long-distance retrograde tracks and stability evaluation indexes of the gravitational wave detection configurations are further established, so that the target stability of the gravitational wave detection configuration corresponding to each long-distance retrograde track is explored, and then a gravitational wave detection configuration design result utilizing the earth-moon long-distance retrograde tracks is generated. Therefore, the problems that the space gravitational wave detection configuration is relatively single and the diversity of gravitational wave detection configuration design is reduced due to the fact that most gravitational wave detection tasks in related technologies adopt circular orbit and regular triangle configuration are solved.

    本申请涉及航天动力学与星座构形设计技术领域,特别涉及一种利用地月远距离逆行轨道的引力波探测构形设计方法,包括:根据圆型限制性三体模型的动力学方程确定周期轨道稳定性理论;建立圆型限制性三体模型中远距离逆行轨道的微分修正,利用微分修正和周期轨道稳定性理论分析远距离逆行轨道特性;进一步建立利用地月远距离逆行轨道的引力波探测构形及其稳定性评价指标,从而探究每个远距离逆行轨道对应的引力波探测构形的目标稳定性,进而生成利用地月远距离逆行轨道的引力波探测构形设计结果。由此,解决了相关技术中的大多数引力波探测任务均采用圆轨道和正三角形构形,导致空间引力波探测构形较为单一,降低引力波探测构形设计的多样性的问题。
