Head Dzhuman Bohdan B., Доктор технічних наук Registration Date 25-03-2026 Organization Lviv Polytechnic National University popup.description1 The aim of the project is to provide comprehensive monitoring of deformation processes in the territory of the Rivne NPP, which is critically necessary to ensure the safety of the facility's operation, identify potential risks to the environment and the population, as well as to take timely measures to minimize the impact of technogenic factors. The project will develop a monitoring system that will allow tracking both natural and technogenic changes that may affect the stability and safety of the operation of the territory around the Rivne NPP. popup.description2 At the reported stage of the research project, a comprehensive study aimed at the analysis of contemporary deformation processes and the development of a local model of the Earth’s gravity field and geoid was carried out based on the integration of heterogeneous geodetic data. Long-term time series of permanent GNSS observations, results of precise leveling, as well as auxiliary satellite and gravimetric data were processed and analyzed. The feasibility of their joint use was substantiated with regard to data accuracy, spatial configuration, and temporal representativeness. An approach for selecting optimal methods for local gravity field and geoid modeling depending on the density and distribution of the available observations was developed, enabling the reduction of modeling errors and improving the consistency of the results. The obtained results demonstrate the capability to reliably determine vertical and horizontal surface motions and to achieve a level of geoid accuracy sufficient for high-precision geodesy, geodynamic studies, and engineering monitoring applications. It is shown that the proposed approaches have significant scientific and practical value and can be effectively applied to the development and modernization of the national geodetic infrastructure of Ukraine.
