基于NRHO的月球全球定位系统星座研究
Research on NRHO-Based Lunar Global Positioning System
摘要
Abstract
In order to meet the increasing requirement of lunar global positioning services for future lunar exploration and exploitation missions,the Lunar Global Positioning System(LGPS)using the Near Rectilinear Halo Orbit(NRHO)as a reference orbit is proposed.First,multiple constellation config-uration schemes are designed,considering configuration parameters such as orbit distribution,satellite number,orbit size,etc.Then,the impact of different constellation configuration parameters on the navi-gation performance of the LGPS constellation is analyzed,including the number of visible satellites,the lunar global coverage characteristics and the Geometric Dilution of Precision(GDOP,σGDOP).Simula-tion results show that,compared with the Halo orbit case,the NRHO-based LGPS is superior in the con-tinuous coverage and positioning accuracy(σGDOP<3)within the lunar high latitude region,especially in the lunar polar region.This study can provide technical reference on the navigation and positioning service for future lunar exploitation missions.关键词
