Monitoring of crustal movements in Ukraine using the network of reference GNSS-stations
Journal Title: Геодинаміка - Year 2017, Vol 23, Issue 2
Abstract
The main goal of our research was to identify the features of the spatial distribution of crustal movements in Ukraine using GNSS technology. Methods. As the initial date for investigation were the observations of 4 years (2013-2016) from over 120 reference stations in Ukraine. The cumulative solution was estimated by program GAMIT/GLOBK. For reference (real), we have taken solutions from EPN Analysis Combination Centre. By comparing the real coordinate and coordinate determined in our cumulative solution we compute RMS of the positioning. Results. The RMS analysis revealed that the received cumulative solution may be used for regional and local geodynamic studies, geophysical interpretation and for many practical applications in geodesy. Based on the estimated horizontal components of velocities, their vectors were constructed on the digital tectonic map of Ukraine. Horizontal rates (22-25 mm/yr) show a clear trend - a dextral character. Movement components are in the direction of Voronezh crystalline massifs. For the vertical component of the relative site velocities, accuracy will increase with an increase in the time interval of GNSS observations. Scientific novelty and practical significance. For the first time the digital tectonic map of Ukraine was prepared with vectors of horizontal velocities of GNSS stations. The values of the determined velocities are homogeneous and with the increase of the observation interval, it will be possible to determine the peculiarities of the movements of the earth crust on the territory of Ukraine and in the future to create a regional geodynamic model of Ukraine.
