The possibility of the GNSS data application has been studied based on the results of data processing of seven sessions recorded from day of year (DOY) 094th to 1ooth in 2010 at the BAKO, COCO, NTUS, LHAZ Stations and on the consideration of the relevant parameters. - The GLONASS data (Or GLONASS system) fully meet requirements in establishing national reference system. In geodynamic study, the GLONASS data are effective tools to support and examine the results of the GPS data processing. As part of the integrated GPS/GLONASS data file, the GLONASS data contribute to improve the accuracy, reliability during the integrated data processing. - The GPS data (Or GPS systems) and the integrated GPS/GLONASS data fully meet the requirements to determine the crustal movement.
