摘　　要：嫦娥探测器轨道测定技术既是成功完成工程任务的基础,也对月球科学研究起着重要作用。嫦娥探测器的轨道测定与地球航天器的轨道测定有诸多不同之处,本文介绍了绕月球探测与绕地球探测在测定轨技术方面的差异,并介绍了基于"嫦娥一号"、"嫦娥二号"月球探测器建立月面地形以及月球重力场模型的研究进展,最后分析了"嫦娥二号"平动点飞行试验以及小行星探测试验的测定轨能力。这些技术不仅在月球探测工程中起到关键作用,对我国后续深空探测也有很好的借鉴意义。Tracking and orbit determination for Chang＇e probes is the foundation for the success of lunar exploration missions as well as study of planet science. Tracking and orbit determination for Chang＇e probes is different in many aspects from tracking and orbit determination for spacecraft circling the earth. This paper introduces the difference between lunar exploration and earth exploration in tracking and orbit determination technology, and introduces pro- gress of lunar topography model and lunar gravity field model based on Chang＇e-1 and Chang＇e-2 lunar probes. Fi- nally, tracking and orbit determination capability for Chang＇e-2 libration flight trial and asteroid exploration is ana- lyzed. The technologies play significant roles in China;s lunar exploration projects and are valuable for reference to follow-up deep space exploration.
