卫星重力梯度数据用于精化地球重力场的研究

Application of Satellite Gravity Gradiometry Data to the Refinement of the Earth's Gravity Field

确定厘米级大地水准面和发展超高阶地球重力场模型是现代物理大地测量的主要科学目标之一。卫星重力梯度测量的实现将为这一目标做出重大贡献。文章着重评述这一领域的研究进展 。

In recent times, one of the primary scientific objectives of physical geodesy is to determine the geoid with centimeter level and to develop the ultra high global earth's gravity field model, and for this purpose satellite gravity gradiometry is one of the most promising techniques. This paper first comments on the main progress of satellite gravity gradiometry, and then discusses some theories and methods for refining the earth's gravity field using satellite gravity gradiometry data.
