linear-angular measurements

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.

Purpose. Investigation of daily movement of GNSS station BRGN of GeoTerrace reference network of Institute of geodesy Lviv Polytechnic National University, by the results of GNSS and linear-angular measurements in order to exclude such movements of geodynamic observations. Methodology. At first step reference network have been created. It included 2 pillars of Beregany geodetic base line (P1, P2). For determination of precise coordinates of these pillars, static GNSS observations were done with use of double frequency receivers.

This paper analyzes the problems that occur with the current classification of state geodetic networks in the modern world.
