Quality assessment of GNSS coordinates outside the SIGNAL network coverage

V diplomski nalogi predstavljamo rezultate terenske izmere GNSS izven območja državnega omrežja stalnih postaj SIGNAL. Problematično območje pokritosti predstavlja celoten obmejni pas med Slovenijo in Italijo. Kakovost določitve koordinat smo preverili na dveh lokacijah v Italiji. Prvo delovišče je bilo izbrano v Trbižu in drugo pri Belopeških jezerih. Na vsaki lokaciji smo z dvema sprejemnikoma GNSS naredili statično izmero GNSS in RTK-metodo izmere. Opazovanja statične izmere GNSS smo naknadno obdelali v programu Leica Infinity z različnimi kombinacijami navezav na stalne postaje omrežja SIGNAL (Bovec, Radovljica in Beljak) in na začasno bazno točko, ki je vzpostavljena v Mojstrani. Cilj naloge je bilo prikazati kakovost določitve položajev točk z različnimi metodami GNSS na kritičnem območju omrežja SIGNAL, kjer VRS določijo z ekstrapolacijo. The thesis presents the results of field GNSS measurements outside the area covered by the SIGNAL network. The entire border region between Slovenia and Italy presents this type of a problematic area. For better representation of the measurements two locations in Italy were chosen for testing. The first worksite was in Tarvisio and the other at the Lakes of Fusine. At each location two GNSS receivers were set up and each receiver made a static GNSS and a RTK measurement. The static measurements were subsequently processed in the Leica Infinity programme using different combinations of connections to the permanent SIGNAL stations (Bovec, Radovljica and Villach) and a temporary basis point established in Mojstrana. The aim of this thesis was to demonstrate the quality of the determinating positions using the GNSS methods in the critical areas, where interpolation cannot be used for VRS.
