摘要
简述了卫星重力梯度测量技术的基本原理和GOCE数据特点;基于三个不同的重力场模型,采用不同阶次,联合卫星测高平均海面高模型分别推算出全球海面地形,并对结果作了比较分析;探讨了卫星重力梯度测量技术在海洋科学各相关领域的具体应用前景,指出卫星重力梯度测量技术的发展将为海洋科学发展带来巨大的变化。
The basic principle of satellite gravity gradiometry technology and the characteristic of GOCE data were presented briefly.Combining a mean sea surface height model（MSS_CNES_CLS_10）,several sea surface topography models over the global ocean were calculated separately based on different degree of three gravity field models,while the results were compared and analyzed.The specific application prospect of satellite gravity gradiometry in relation to respects of ocean science was discussed,and that the development of satellite gravity gradiometry will bring about a great change for ocean science was pointed out.
