In this work test of quantitative and qualitative analyses of observation on GPS/GLONASS permanent station Wroclaw was introduced. Test of quantitative analysis of activity of station Wroclaw was prepared on the base of the reports generated by regional data centers operated in frame of EUREF project. Realization of qualitative analysis depended on influence of external conditions (meteo and height of ground water level) onto determined coordinates of antenna. Executed analyses in frames of quantitative opinion proved high, amount to suitably 92.9% and 95.9% of availability of hourly and daily data. From moved analyses it results, that it was been possible to receive GPS data on average by 97% of time, and full, 24-hourly observation data are available for 91% of all sessions. The analyze of influence of ground water level onto determined height of antenna, did not disclose essential dependence among this two conditions. Different external factor, meteorological conditions near antenna did not show influence onto marked coordinates. The opinion of activity of station “WROC” in frame of EUREF service (reports from European IGS data center) shows 77% reliability. Executed analyses proved high correctness in efficiency of collection of observation data, and efficiency in data distribution process for GPS/GLONASS permanent station Wroclaw.
