摘要: 针对月球南极卫星导航星座构型开展研究。对比了月球环月轨道和三体轨道的动力学特性,提出了适用于南极导航的以近直线晕轨道(Near-rectilinear Halo Orbit,NRHO)和偏心率冻结轨道(Elliptical Lunar Frozen Orbit,ELFO)为主的混合异构星座思路。构建了以导航星座值(Constellation Value,CV)和建设成本为双重优化目标,以不同轨道内的卫星数量、ELFO卫星轨道参数作为决策变量,采用带精英策略的非支配排序遗传算法(Non-dominated Sorting Genetic Algorithm Ⅱ,NSGA-Ⅱ)进行月球南极导航星座构型优化设计。仿真结果表明,2颗NRHO卫星+4颗ELFO卫星的星座构型,可实现月球南极CV值95%、定位精度50m。相关成果可为后续月球南极导航星座的研究及工程应用提供参考。

Abstract: The configuration of the Lunar South Pole satellite navigation constellation is studied. Comparing the dynamic characteristics of the lunar orbit and the three body orbit, a hybrid heterogeneous constellation mainly composed of NRHO (Near-rectilinear Halo Orbit) and ELFO (Elliptical Lunar Frozen Orbit) is proposed to support Lunar South Pole navigation. A dual optimization objective function of constellation value and total costs is constructed, with the number of satellites in different orbits and ELFO satellite orbit parameters as decision variables. The NSGA-Ⅱ (Non-dominated Sorting Genetic Algorithm Ⅱ) algorithm is used to optimize the configuration design of the Lunar South Pole navigation constellation. The simulation results show that a Lunar South Pole constellation configuration of 2 NRHO and 4 ELFO satellites can achieve CV value of 95% and a positioning accuracy of 50m. The relevant results can provide reference for the research and engineering application of Lunar South Pole navigation constellation in the future.
