Abstract
The paper presents the results of processing data from a network of permanent stations of the Global Navigation Satellite System (GNSS) of Kashadarya region for the period 2023-2024. The kinematic aspect of movement was considered, in station velocity relative to the reference system, and an assessment of local tectonic movements of the area was made. The Gamit/Globk program was used to estimate the coordinates and velocities of sites relative to ITRF2014 (The International Terrestrial Reference System) . The average value of horizontal velocities relative to ITRF2014 was 27 mm/yr. The obtained local rates relative to Eurasia ranged from -1 to 4.6 mm/g. The results of the obtained horizontal velocities confirmed their tectonic origin and can be used to assess the stress-strain state of the region.
Keywords: GNSS, horizontal movement, seismicity, CORS, GAMIT/GLOBK, RINEX, ITRF2014 .
