利用卫星重力梯度恢复局部地球重力场的研究进展

Study Progress in Regional Gravity Field Recovery Using Satellite Gravity Gradiometry

简述了SGG数据恢复局部重力场的理论本质以及卫星重力梯度边值问题;详细介绍了当前国内外利用SGG进行局部重力场求解的研究进展,并将已有的求解方法总结归纳为三类:模型法、计算法和组合法,同时对各种方法的概念和研究现状作了详细介绍;最后总结了SGG数据求解局部重力场的发展前景和思考建议。

In this paper,the theory nature of determining local gravity field by SGG data and satellite gravity gradiometry boundary value problem were presented briefly;the current research progress both inland and abroad of regional gravity field determination from SGG was introduced in detail,the solving methods were classified three categories：model method,computation method,combination method,and the concept and study status for every method were discussed;in the end,the developmental prospect and advice of local gravity field recovery using SGG data were summarized.
