摘　　要：面向未来近月空间站部署需求,提出了一种三级修正的长期拟周期近直线晕轨道(NRHO)设计方法。首先,设计了新的离散点选取策略,降低了对参数敏感区域的打靶需求,提高了多点打靶法计算多圈次拟周期NRHO的收敛性能。然后,基于NRHO的对称特性,给出了初始拟周期NRHO圈次延续方法和滚动时域长期拟周期NRHO生成方法,根据拟周期NRHO近月点半径设计了修正策略。使用不同的NRHO进行仿真实验,生成了维持500圈约10年的长期拟周期NRHO。仿真结果表明本方法提高了收敛效率,且能有效生成地月空间长期拟周期NRHO。Motivated by the deployment of future space station nearby the Moon,a method including three-level corrections for the design of long-term quasi-periodic near rectilinear Halo orbit(NRHO)is proposed.Firstly,a new discrete point-selection strategy is designed,which reduces the need for shooting in parameter-sensitive areas and improves the convergence performance of multi-revolution quasi-periodic NRHO calculations using multiple-shooting method.Based on the symmetric properties of NRHO orbits,the initial quasi-periodic NRHO continuation method and the receding-horizon long-term quasi-periodic NRHO generation method are given.A correction strategy is designed based on the periapsis radius of the quasi-periodic NRHO.Simulation experiments are performed with different NRHOs and long-term quasi-periodic NRHOs that maintain 500 revolutions for about 10 years are generated.The results show that this method improves the convergence efficiency and can effectively calculate the long-term quasi-periodic NRHO in the cislunar space.
