20.500.12556/RUL-162332 Analiza in izboljšava rezultatov kinematične izmere GNSS diplomska naloga Analysis and improvement of GNSS kinematic measurement results V diplomski nalogi smo primerjali rezultate statične in kinematične RTK-izmere GNSS ter analizirali možnost izboljšave točnosti določitve položajev točk kinematične izmere RTK. Znano je, da so koordinate točk kinematične izmere RTK slabše kakovosti glede na rezultate statične izmere GNSS, kar ima vzrok predvsem v, še vedno prisotnih, sistematičnih pogreških v okviru mrežnih rešitev izmere RTK. V nalogi nas je zanimalo, ali je možno zasnovati metodo izmere RTK tako, da bi bila točnost rezultatov bolj primerljiva z rezultati statične izmere. Metodo smo preizkusili na primeru treh točk na strehi Fakultete za gradbeništvo in geodezijo v Ljubljani. S kinematično izmero pridobljene koordinate RTK smo primerjali s koordinatami, določenimi s statično izmero, in iskali prisotnost sistematičnega zamika med obema nizoma koordinat. Ugotovili smo, da je ta sistematični zamik prisoten in smo ga računsko odstranili. Z vrednostmi RMS razlik med obema nizoma koordinat, prvimi določenimi s kinematičnimi metodami izmere in drugimi določenimi s statično izmero, smo pokazali, da se po odstranitvi zamika izboljša točnost končnih koordinat točk, določenih z izmero RTK z navezavo na državno omrežje stalnih postaj GNSS, SIGNAL. In the thesis, we compared the results of static and kinematic RTK GNSS survey and analysed the possibility of improving the accuracy of point positioning in kinematic RTK measurements. It is known that the coordinates of points from kinematic RTK measurements, compared to static GNSS measurements, are of lower quality, mainly due to the still-present biases within network-based RTK solutions. We were interested, whether it is possible to improve an RTK survey so that the accuracy of results would be more comparable to that of static measurements. The method was tested using three geodetic points on the roof of the Faculty of Civil and Geodetic Engineering in Ljubljana. We compared the coordinates obtained from the kinematic RTK measurements with those determined by static measurements and looked for the presence of systematic offset between the two sets of coordinates. We found this systematic shift to be present and removed it computationally. With the RMS values of the differences between the two sets of coordinates, the first determined by kinematic measurement methods and the second determined by static measurement, we showed that after removing the shift, the accuracy of the final coordinates of the points determined by RTK measurement by linking to the national network of permanent GNSS stations, SIGNAL, improves. diplomske naloge geodezija GNSS GNSS-RTK VRS MAC RMS sistematični pogrešek točnost graduation thesis GNSS GNSS-RTK VRS MAC RMS systematic error accuracy true false false [M.
