V nalogi obravnavamo kakovost določitve 3D položajev točk na višjih nadmorskih višinah, ki smo jih določili z RTK-metodo izmere. Izmero smo naredili na območju med Cerkljami na Gorenjskem in Krvavcem, ki smo ga izbrali zaradi velike višinske razlike med točkami, katerim smo določali položaj. Najprej smo določili položaje točk z RTK-metodo izmere ob uporabi storitve VRS omrežja SIGNAL, nato smo vzporedno izvajali še hitro statično metodo izmere GNSS, kjer smo na eno izmed točk na delovišču sami postavili bazno stojišče. Rezultate izmere smo primerjali s predhodno izvedeno statično izmero GNSS, ter nadalje primerjali koordinat točk, ki smo jih določili na različne načine. Cilj naloge je bil pokazati, kako se skladajo 3D položaji točk različnih izmer, ter raziskati, ali na višjih nadmorskih višinah z RTK-metodo izmere ob uporabi opazovanj omrežja SIGNAL pridobimo dovolj dobre rezultate določitve položajev točk. The graduation thesis deals with the quality of 3D point determination using RTK method on higher altitude points’ locations. The field work was bound up with the areas between Cerklje on Carniola and Krvavec. This area was chosen by virtue of the large difference in heights between the points that GNSS-positioning has been performed. First the position of the points was determined with the VRS RTK-method in the national GNSS continuously operating reference network SIGNAL. Furthermore fast static method for point position determination has been performed to acquire positions for points included in the comparison study. We compared positions from RTK where previously static GNSS method results were used as the reference. The goal of the thesis was to show the consistency of 3D positions of points at different altitudes. Finally, the experience of point positioning at higher altitudes of the SIGNAL network has been gained with first assessment of position quality of points from higher altitudes.
