"鹊桥"通导遥星座系统与脉冲星联合导航研究
Research on Integrated Navigation Utilizing Queqiao Communication Navigation and Remote Sensing Constellation System with Pulsars
摘要
Abstract
To address issues such as strong dependence on ground-based measurement and control in high-precision naviga-tion of spacecraft in cislunar space,a high-precision navigation approach integratings X-ray pulsar and Queqiao constellation in-formation.By coupling the X-ray pulsar observation data with the spacecraft ranging information provided by Queqiao Communication-Navigation-Remote Sensing constellation and incorporating cislunar orbital dynamics models,a joint naviga-tion observation model of the Queqiao constellation and pulsars was constructed,and the navigation accuracy of the circumlunar orbit and the Earth-Moon L1 libration point Halo orbit was analyzed.Simulation results demonstrate that improvements of 90.11%and 88.73%in position accuracy for the two orbits have been achieved with the accuracy increasing from 1.73 km and 2.10 km to 187 m and 236 m compared with traditional X-ray pulsar navigation(XPNAV).The joint navigation method pro-posed in this paper can significantly enhance the navigation and positioning performance,and provide theoretical reference and technical support for navigation applications in tasks such as cislunar space resource exploitation.关键词
