The purpose of this work is to prove the necessity and possibility of returning to the orthometric system of heights in Ukraine and to substantiate the ways of solving this problem. The method of achieving the goal is provided by theoretical studies of existing methods of astronomical and geodetic leveling, modern methods of forecasting neotectonic processes, GNSS accuracy and geometric leveling.

The article presents the aspects of historical development of monitoring of Tereble-Ritska hydroelectric power station (HPP), which led to the need of establishing an automated system of geodetic monitoring (ASGM) of deformations of the water pipeline and other structures. Since 2018, the system has been automated and the instrumental part continues to be expanded. Thus, as of 2022, the instrumental part of ASGM includes 3 main components, namely: linear-angular measurements with the determination of meteorological parameters, satellite GNSS measurements, and piezometric measurements.

The purpose of this work is to show the prospects and the need to continue work in Ukraine on the creation of anti-aircraft systems and astronomical geodetic leveling (a combination of astronomical and high-precision geometric leveling), using GNSS and instruments that provide accurate measurements of deviations of the temple 0.1 geodynamic landfills and man-made, which create for the construction of a height foundation for the construction and operation of extremely important facilities.

The emergence of satellite observations was marked by their widespread use to determine the velocities and direction of horizontal motions of lithosphere plates (modern kinematics of lithosphere plates), which allowed to research the deformation processes at the global and regional levels. Today, permanent GNSS stations cover a large part of the land area. Since many of these stations have accumulated a large amount of daily observation over 20 years, it is possible to trace the deformation processes of certain areas.

The purpose of the research. Elaboration of practical recommendations concerning creation of a geodesic markup construction base with GNSS technologies, including Real Time Networks (RTN) methods. Methodology. To investigate the accuracy of the recommended solutions, different kinds of research were made, including a practical one. It was conducted on the construction site by marking the axis from two base lines, previously indicated by a GNSS receiver in such a way, so they coincided with the x and y axes of the general site’s plan.

Purpose. The purpose of this study is to determine the horizontal movements of the earth surface in the vicinity of the main waterworks Dniester HPPS and the surrounding area using technologies of satellite monitoring by global navigation satellite system (GNSS). The territory is under the influence of anthropogenic impact of HPPS cyclical operating mode. To assess the accuracy of horizontal displacements of HPPS water intake at points with limited reception of satellite signals using compliant data of satellite and linear-angular measurements.

Purpose. This study assumed: experimental determination of the accuracy of coordinates of points of the geodetic network dual-frequency GNSS receivers from different manufacturers under different conditions of observations using RTK-technology; study connectivity and receiving a fixed solution RTK mode with extra-long bases (200 km). Methods. To investigate the accuracy of the coordinates in the experimental work were involved six surveying crews ukomplektovuvalysya six receivers of different manufacturers.

Purpose. The purpose of this work is to study the possibility of restoring urban traverse networks using high-precision technologies in satellite mode, real-time kinematics. Method. To achieve this goal were involved surveying six teams that were equipped with six receivers of different manufacturers. The observations were made as the "static" and in RTK-mode, and, determining the coordinates of points traverse the network Chernihiv mode performed by permanent RTK networks with different configurations and mount points.

Purpose. The purpose of this work is to study the effectiveness of using satellite technology in real-time kinematics mode for work performed to determine the areas of land of different size within a settlement. Methodology. To realize this рurpose we have conducted experimental research on satellite observation points and triangulation of polygonometry in Chernihiv and the region. During the research it was assumed to get the control coor¬dinates on the basic points from static observation.
