Determination of gravity field from horizontal gradients of gravity

A method was developed, based on integration of horizontal gradients of gravity W-zx and W-zy to predict gravity at all points of a torsion balance network. Test computations were performed in a typically. at area where both torsion balance and gravimetric measurements are available. There were 248 torsion balance stations and 1197 gravity measurements on this area. 18 points from these 248 torsion balance stations were chosen as fixed points where gravity are known from measurements and the unknown gravity values were interpolated on the remaining 230 points. Comparison of the measured and the interpolated gravity values indicates that horizontal gradients of gravity give a possibility to determine gravity values from torsion balance measurements by mGal accuracy on. at areas.
