摘要：The data obtained during GPS observations is the basis for the creation of local quasigeoid models and obtaining differences in the heights of normal and ellipsoid surfaces of WGS-84. The network of satellite base stations located in the Rostov region is used as points of the state geodetic network (SGN). The gravimetric model is used as a model of the quasigeoid height (QH). The model of the quasigeoid is calculated and developed on the basis of gravimetric data. Five base stations located within the city of Rostov-on-Don are selected to obtain the normal heights of SGN points. The above points are recalculated from the local system to the WGS-84 system. The equation of the plane, approximating the local quasigeoid is constructed. The gravimetric heights of the quasigeoid are obtained by substituting the coordinate values of each point. The calculation of the normal heights of points is made after an estimation of the model accuracy.
