国外地月空间通信与导航服务系统发展研究OA北大核心CSTPCD

As lunar exploration continues to be trendy,the demands for cislunar space communica-tions,navigation,and network services increase rapidly.The United States and Europe have be-gun to promote commercial efforts to establish cislunar space communications and navigation service systems.The development of foreign cislunar space communications and navigation sys-tems are comprehensively analyzed,outlining LunaNet,Moonlight and other plans promoted by government space agencies,as well as CAPSTONE(Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment),Lunar Pathfinder,Parsec and other system and technology research projects implemented by commercial companies under the guidance of government agencies.On this basis,key technologies including deep space optical communica-tions,lunar surface cellular communications,and network security are analyzed.Trends in the development of these systems are presented,highlighting the acceleration of service develop-ment,the integration of communication and navigation,and attention to the formulation of inter-national standards.Some insights and recommendations for future development of these systems are put forward,such as planning a long-term development roadmap,enhancing international co-operation,and fostering public-private partnerships.These suggestions can serve as references for the development of cislunar communications and navigation systems.
