The graduation thesis deals with the quality estimation of simultaneous acquisition of 3D
coordinates using GNSS RTK method. The aim is to acquire the knowledge of the possibility
of the internal network quality improvement by RTK-measurements performed at different sites
at the same time. For this purpose we need several operators at different sites, which are
synchronized in timings of measurements.The test consists from a set of several
measurements acquired by RTK-method with different timing and different occupation
durations. For the experimental tests the network of three points has been established and
determined by a static GNSS method. On the same locations coordinates were further
determined using simultaneous measurements of multiple receivers as well as by successive
measurements with different timings of coordinate’s determination. RTK coordinates were
compared first with coordinates from a static determination. Second comparison of coordinates
of simultaneous and successive determination as well as coordinates with different occupation
durations was performed. From the experimental test we can conclude simultaneous RTKmeasurements,
if possible, enable better internal precision achievement. Second conclusion
is that longer occupation duration leads to the coordinates of a better quality.
