|Summary:||The elevation of GPS measurements is the geodetic height relative to the WGS-84 ellipsoid of the earth. Gravity exploration needs the normal height. The authors introduce the principle of using polynomial surface fitting method to fit the height anomaly. Using leveling height from level measurement assesses the precision of the fitting normal height. This paper sum the application effect of GPS fitting elevation in gravity exploration.|
