中国月球探测任务轨道确定技术及发展综述

A Summary of Orbit Determination Techndogy for Chinese Lunar Exploration Project

摘要: 月球探测器的轨道确定是完成月球探测任务的基础，在我国月球探测任务的引领下，在我国深空测控体系发展的同时，轨道确定技术也得到了快速的进步。从时空参考框架和动力学模型两个方面介绍了我国月球探测任务轨道确定技术的发展过程，基于时空参考框架的优化及动力学模型的改进，我国月球探测器的轨道确定能力及精度也不断提升，这对于当前及后续的月球探测任务都有很好的借鉴意义。

Abstract: The orbit determination of lunar probes is the basis of lunar exploration. With the development of deep space TT&C (Tracking, Telemetry and Command systems) in China, the technology of orbit determination has made rapid progress driven by the lunar exploration mission. The space-time reference and dynamic mode are presented for the development of orbit determination. Based on this, the orbit determination performance and precision of lunar probes are continuously improved in China, which is a good reference for lunar exploration mission for now and future.
