Abstract

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.
