Purpose. Investigation of daily movement of GNSS station BRGN of GeoTerrace reference network of Institute of geodesy Lviv Polytechnic National University, by the results of GNSS and linear-angular measurements in order to exclude such movements of geodynamic observations. Methodology. At first step reference network have been created. It included 2 pillars of Beregany geodetic base line (P1, P2). For determination of precise coordinates of these pillars, static GNSS observations were done with use of double frequency receivers. After finalizing of session of GNSS observations, precise robotic total station Leica TCRP1201 was installed on the point P1. In parallel, temperature and pressure measurements were conducted, and atmospheric corrections were determined on the processing stage. Processing of linear-angular (baseline P1–BRGN) and satellite measurements (P2–BRGN) was done in specialized software Leica Geo Office. After data processing comparison and analysis of the results of daily station movement of BRGN reference station have been done, two methods were used for this purpose. Results. Methodic of daily movement of GNSS station is proposed with joint usage of linear-angular and satellite measurements. By the results of permanent linear-angular measurements by the duration of 25 hours are determined that station BRGN is moving within 3 mm in horizontal plane. During the dark and daytime movement is going to the different directions. Results of satellite observations are correlated with the results of linear-angular measurements. However, dispersion of satellite measurements is much higher. This confirms that short-term station movement is very complicated to be determined using only satellite observations, and this kind of measurement can be used only as control measurements. High dispersion may be caused, by the satellite observations distortion due to different factors. Is determined that Sun azimuth has influence to the direction of BRGN pillar movement. Movement is going to opposite direction from the direction to the Sun. It caused by the temperature difference on the lighted and unlighted, by the Sun, parts of pillar. Obviously it leads to the deflection of the pillar aside to the less heated part of pillar, because metal during the heating is expanding. Originality. By the results of investigation, the methods of daily reference station movement determination is developed and approved. One promising avenue for further research might identify patterns of daily reference station movement in different seasons and develop techniques to exclude the results of geodynamic observations. Practical significance. The developed methods of daily reference station movement determination can be used for investigation and prognoses of daily GNSS stations movements of geodynamic polygons.
