Abstract

This scientific article researches method for perfection and modernization of state vertical system based on results of experiments of quasigeoid model VIGAC2014 that allows to obtain highly accurate normal heights on mainland and islands. Determination of GPS/first and second leveling points, on which differences between gravimetric height anomaly (got from the quasigeoid model VIGAC2014) and GPS/leveling height anomaly have enough small values, allows to solve parallel tasks of fitting of quasigeoid model VIGAC2014 to GPS/leveling quasigeoid model and modernization of the state vertical system HP72 based on fitted quasigeoid model VIGAC2014. By this approach, we will recorrect normal heights correspoding to constructed quasigeoid model for first and order leveling points on which differences between gravimetric height anomaly and GPS/leveling height anomaly have big values exceed error limit.
