摘要
对月球航天探测的主要情况作了回顾,概要介绍月球地形测绘和月球大地测量。首先介绍月球大地测量(Selenodesy)的定义和方法。月球大地测量的特点是它的观测数据绝大部分都要依靠航天探测器或环月、绕月卫星来获取。月球大地测量的内容可以考虑有三个方面:一是在月球上给出一个有确定定义的坐标参考系,并在其中布测一个控制网;二是确定这一月球参考系的大地测量几何和物理常数;三是求定月球的外部重力场。最后概述月球地形测绘的特点。
In this paper main history of lunar spatial exploration are introduced. Lunar topography surveying and lunar geodesy are reviewed in the paper. The definition and technology of Lunar Geodesy （Selenodesy） is briefly described. Then the lunar topographic surveying and its behaviors are presented. One of the characteristics of selenodesy is that most of its observation data comes from the space probes or the satellites flying around or by the moon. It may be considered that there are three parts of the selenodesy, i.e. the first part includes a lunar coordinate reference system with correct definition, and in which a control network of selenodesy is measured. The second one is the determination of geometric and physical constants in the lunar coordinate reference system. The third one is the determination of lunar gravity field.
