Processing of GNSS data in Gamit/Globk: On the example of the reference stations of the Uzbekistan network

The article presents the results of processing, a preliminary assessment quality measurements, and accuracy coordinates points reference network Uzbekistan (MAGK, FARG, JARQ, URGA). Observation data GNSS were processed using GAMIT/GLOBK v.10.71 software package by applying standard procedures for position velocities estimation relating to ITRF2014 global frame. horizontal compared with latest versions tectonic models such as ITRF 2014, GEODVEL 2010, NNR - MORVEL 56. Analysis point time series confirmed good measurements in program. calculated solutions had coordinates, uncertainties uncertainty, repeatability, at level 1-3.2 mm 3.2-6.5 height. However, analysis comparison need further compaction regional satellite network, especially western part territory, taking into account new model modern movements region.
