摘要
确定高精度和高分辨率地球重力场模型是现代大地测量的基本目标之一,卫星重力计划就是基于这一目标实施的。文章简单地评述了卫星重力的发展现状,介绍了三颗专用的重力卫星,给出了卫星重力测量的基本原理,最后比较了几种由重力卫星资料得到的地球重力场模型。
One of the fundamental scientific objectives of modern geodesy is to determine the high precision and high resolution earth gravity field. The satellite gravity project is just for this object. In the paper, we discussed simply the development of satellite gravity measurement, and introduced three styles of gravity satellites, described the theory of satellite gravity measurement, and compared several different gravity field models obtained from the satellite gravity data in the end.
