The aim of our thesis was to check the effect of distance from the continuously working
GNSS reference station on the accuracy of positioning when using static and kinematic
GNSS surveying methods. Field measurements were carried out at six points in the area
near Ljubljana and Vrhnika at distances from 5 to 25 kilometres from the GNSS continuously
working reference station in Ljubljana. Coordinates of selected points were determined using
rapid static and RTK measuring method. In RTK method a virtual reference station VRS
created near the worksite and permanent station GSR1 were used as reference stations.
When processing the rapid static observations VRS located at different distances from the
worksite was used as the reference. With rapid static we also examined the rule: the
observation time = 10 min + 1 min · b, trajanje where b was the distance from the reference
station. We found out that the observation time needs to be longer if we are further away
from the reference station.
