Optimum point model of the Earth gravity field compiled on the basis of absolute gravity values
An optimum point model of the global gravity field was compiled on the basis of data for absolute values оf gravity, the model was composed of point, masses. Optimum parameters of the masses were determined by the least squares method This model is unique and stable for the used set of data and provides the best description of the field with least number of parameters of the sources. It approximates the used absolute values of the gravity with a mean square error of about 40 mGal, and only for data from the USA territory - 30 mGal.
