Summary:

The paper presents the method of testing the precision and accuracy of satellite measurements made with the Trimble NetR9 receiver model with a Zephyr Geodetic Model 2 antenna (TRM55971.00 TZGD), which was additionally equipped with a snow shield. The tests covered the results of static measurements in the form of geocentric coordinates XYZ, calculated with the automatic POZGEO service, operating under the ASG-EUPOS system. The observations were made in measuring sessions of 1h, 2h, and 3h. The statistical tests were conducted to check if the distributions of their errors correspond to normal distribution, which would determine the accuracy of the performed test calculations and measurements, and consequently the usefulness of the tested satellite receiver in geodetic surveys.
The correctness tests of the executed measurements and calculations applied three statistical tests: the parametric test, the D' Kolmogorov statistic, and the V and V' Kuiper statistics. The conducted analyses and studies provided conclusions on the correctness of the survey and calculation results and the usefulness of the tested measurement system in the execution of various geodetic operations.
