载人月球探测深空站布局体系

针对载人月球探测,在我国现有深空测控资源的基础上,结合其他航天组织,如NASA (National Aeronautics and Space Administration,美国国家航空航天局)、ESA(European Space Agency,欧空局)等分布在全球的深空测控资源,提出了全球深空站布局体系.该体系包括我国深空站在内的8个地面站,大体形成“南四北四,均匀分布”的格局.并以美国“重返月球”计划深空站布局为参照,对比分析了布局体系的测控覆盖、三向测量和干涉测量共视弧段,讨论了布局干涉测量不同观测站三角的测角精度,可以为后续载人月球探测任务提供支持和参考.

Deep Space Station Distribution System for Manned Lunar Exploration

A global deep space stations system is proposed to meet the demand of manned lunar exploration.The system combines deep space tracking and telecommunication stations in China with resources in other large aerospace organizations such as National Aeronautics and Space Administration (NASA) and European Space Agency (ESA).There are totally 8 stations in the system.Four stations are located in the northern hemisphere and the other four are in the south.They generally form uniform distribution.By drawing reference to the station system of "return to the moon" project proposed by NASA in 2005,the coverage of tracking,three-way measuring and interferometry between these systems are discussed.The angular determination accuracy of each observationtriangle in the systems is also analyzed.The whole idea may give some new vision and reference for future manned lunar exploration.
