The object of research is the study and determination of the parameters of the Earth's shape and gravitational field (construction of a quasi-geoid model on the territory of Ukraine). The purpose of the work is to build a quasi-geoid model on the territory of Ukraine to ensure the definition in the national reference system of heights of geodetic points and localities using GPS-leveling methods when performing topographic and geodetic and cadastral works, as well as solving navigation problems by public administration, local government all levels and organizations. Within the framework of the project works on survey of benchmarks and points of the existing State leveling network, II and III classes, built according to "Basic provisions on the state geodetic network of the USSR" of 1954-61, satellite geodetic observations at points of leveling network, calculation of vectors bases between grid points, grid alignment and calculation of coordinates of leveling grid points, compilation of catalogs of grid point grid coordinates in USK-2000 and ITRS / ITRF2014 coordinate system, modeling of quasi-geoid surface on the territory of Ukraine. Construction of the UKG-2017 quasi-geoid in the USC-2000 coordinate system and the Baltic Altitude System in 1977 allows to determine the heights of the quasi-geoid above the Krasovsky ellipsoid with a mean square error of less than 0.05 m. into the European economic system, participation in international scientific research of global ecological and geodynamic processes, study of the figure of the Earth and the gravitational field and mapping of the territory of Ukraine. Research method - satellite observations, mathematical processing of satellite observations, modeling of the quasi-geoid surface on the territory of Ukraine.
