无基点海洋重力测量数据归算补救方法
A remedy method for the data reduction of marine gravimetry without base point information
摘要
Abstract
In order to treat the data reduction in marine gravimetry without base point information,on the basis of analyzing and evaluating the reliability and validity of the geopotential model and the satellite altimeter-derived gravity model released recently in the world,it is suggested to use these two types of model as a control datum for the medium-long wave of marine gravity field,and a remedy method is proposed for the data reduction of marine gravimetry without base point information.The calculation flow and step of data reduction are described.The adaptation conditions and accuracy level of applying the remedy method are analyzed and discussed.The validity of the suggested remedy method is verified using several sets of data from marine gravity survey,and it is shown that it is feasible and effective to apply the geopotential model and the satellite altimeter-derived gravity model to the remedy processing of marine gravimetry data without base point information.关键词
