Monitoring of crustal movements in Ukraine using the network of reference GNSS-stations

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.

Estimation of the accuracy regional combined GNSS solution

The main goal of our research was to estimate the accuracy regional combined GNSS solution by changing the duration of observations and configuration of the reference stations network. Methods. As the initial date for investigation were the results of 4 weeks from 119 reference stations in Ukraine. These results of observation were used for design four networks with different sets of reference stations and for each network was calculated the combined solutions.
