Abstract

This Journal will present a justification for the necesity to build the national space coordinates reference system, which is actually modeling the quasigeoid with high accuracy. At the same time, it will also prove that the obmission of geodetic height of the level I, II national geodetic points coincides with the GNSS points in determining 07 parameters of transfering the coordinates from international WGS84 ellipsoid to national WGS84 ellipsoid, not allowing to receive geodetic height with high accuracy in the national space coordinates reference system (VN20003D).
