RESULTS OF SCIENTIFIC WORK
The method of optimization of geodetic measurements in networks. Methods implemented in the construction of geodetic network Tereblya-Rikskoyi HPS. On the basis of the algorithms built project active network of GNSS stations on the territory of Ukraine. Construct geodetic network to monitor deformations of engineering structures Kanevsky, Dniester, Dniprodzezhynskoyi, Kremechuhskoyi HPS.
Theoretically grounded and implemented in the form of the algorithm method of constructing maps of vertical deformation of the crust. As a result of high-precision leveling maps showing land surface deformation in the Carpathian region.
In 2003, during the eighth Ukrainian Antarctic expedition built on Argentine Islands geodetic network to study geodynamics tectonical fault of the Penola Strait. As a result of two cycles of GNSS measurements (2003-2005) established the earth surface deformation parameters of the Argentine Islands. Built geodynamic model fault blocks.
The theoretical foundations of the earth surface movements of differentiation defined in the time series of GNSS measurements. The model of kinematics motion Antarctic tectonic plate under the influence of various forces. It coordinates the Euler pole Antarctic tectonic plate.
Founder and Head of Multifunctional precise satellite positioning system Geoterrace in Western Ukrainian.
He published more than 150 scientific works, among others two monographs and 8 patents.
