In this graduation thesis we have checked the quality of RTK-point positioning in the coordinate
system ETRS89 with various occupation durations. The occupation durations were related to the
interval from 5 seconds and up to 5 minutes after the successful initialization. The process of
identifying differences has been performed similar to the methodology of RTK-instrument testing
according to the standard ISO17123-8. First we have established a three-point network at the area of
Trbovlje and further performed static GNSS measurements. By several different post-processing
strategies we have acquired coordinates that were used as the reference for further studies. We have
used observations from three permanent stations of the national continuously operating reference
station network SIGNAL, i.e. Trebnje, Celje, Ljubljana and finally also VRS station to acquire final
coordinates from post-processing. Meanwhile we have tried to find out the minimal occupation
duration for quality baseline determination from fast-static measurements. Positions of the three points
were determined using Leica 900 instrument for RTK-method performance. Positions were
determined by several independent initializations and by different occupation durations. We have
found that in the case of the instrument Leica 900 there are no significant differences between
positions of detail points, acquired from different occupation durations after the initialization.
