Analysis of diurnal changes of coordinates of the GPS receiving station ULAZ by programs of RTKLIB and Mathlab

Statistical characteristics of daily variations of the measured coordinates of the GPS-station ULAZ are determined. Conducted initial processing of daily statistics, comparison and statistical analysis of the data station ULAZ 2001 and 2017, Shows a difference of statisticalcharacteristics between the measurement coordinates over 16 years. It is shown that RTKLIB and MATHLAB programs are convenient for processing primary data related to positioning and navigation using GNSS. It was found that further data processing is necessary, which will require the creation of a system for processing large amounts of data.
