Made the analysis of the establishment and operation of scientific geodetic reference range, which consists of two measurement items: 1) the standard of fundamental geodetic network for metrological certification receivers of GPS, and 2) a geodetic test traverse for metrological certification and verification range devices. The possibilities of its development and application was described.
Widespread use of GPS / GNSS technology sets the task of determining the normal (orthometric) heights of points. We know that it is necessary to determine the initial level surface – the surface of the geoid / quasigeoid. Determination of the quasigeoid surface can be performed by: 1) a gravimetric readout in the relevant region and building the regional geoid / quasigeoid; 2) a model of potential of gravitational field of the Earth; 3) an interpolation of quasigeoid’s heights on a surface given by leveling reference points, on which GNSS-leveling is carried.
