Primerjava obdelave opazovanj GNSS v različnih programskih paketih

V diplomski nalogi so predstavljeni rezultati, ki smo jih pridobili z obdelavami GNSS-opazovanj z različnimi programskimi paketi kot tudi metodami določitvami položaja. Na izbranem delovišču smo naredili statično izmero GNSS na šestih točkah in opazovanja obdelali naknadno. Položaj smo določili na relativen in absoluten način. Relativni položaj smo določili z radialno izmero ter izravnavo mreže vektorjev GNSS. Za določitev relativnega položaja smo uporabili programske pakete Leica Infinity, Leica Geo Office, RTKlib ter spletno aplikacijo Trimble Online Processing. Za določitev absolutnega položaja smo uporabili spletno aplikacijo Trimble RTX in RTKlib. Primerjali smo razlike v koordinatah, ki smo jih dobili z različnimi obdelavami. Ugotovili smo, da se rezultati med seboj razlikujejo v velikosti centimetra. This diploma thesis presents and discusses the results obtained by processing GNSS observations using different software and positioning methods. We performed a GNSS static measurement at six points at the selected site and subsequently processed the observations. The position was determined relatively and absolutely. Namely, the relative position was determined through radial measurement and the offset of the GNSS baseline network using the Leica Infinity, Leica Geo Office and RTKlib software packages and the Trimble Online Processing web application. In order to determine the absolute position, we used the Trimble RTX web application and RTKlib. We compared the differences in the coordinates obtained using various types of processing and established that the results slightly differ, but only by a centimetre level.
