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.
