Abstract
V diplomski nalogi smo analizirali kakovost določitve položaja z metodo RTK v omrežju SIGNAL z uporabo različnih mrežnih konceptov in navezavo na eno referenčno postajo. Pri mrežnih konceptih smo uporabili koncept MAC (ang. Master-Auxiliary) in VRS (ang. Virtual Reference Station). Sama kakovost položaja je bila ocenjena na podlagi točnosti koordinat, katera je bila definirana kot razlika med referenčnimi koordinatami in koordinatami pridobljenimi z metodo RTK. Referenčne koordinate so bile pridobljene s statično metodo izmere GNSS. Kakovost metode RTK smo ocenili po standardu ISO 17123-8 po katerem smo tudi ocenili grobo pogrešene koordinate ter jih odstranili iz analiz. Preverili smo do kakšnih odstopanj v kakovosti položaja prihaja pri uporabi istega omrežja postaj GNSS s sprejemniki različnih proizvajalcev. Uporabili smo sprejemnike znamk Leica, Trimble in Javad.

Title:Quality analysis of methods for position determination in active GNSS networks
Abstract:
In this thesis, we analyzed the quality of position determination with the method of RTK in the Slovenian GNSS network SIGNAL. For position determination we used method RTK in various network concepts and using one reference station. We used network concept MAC (Eng. Master-Auxiliary Concept) and VRS (Eng. Virtual Reference Station). The quality of the position has been estimated based on the accuracy of coordinates, which was defined as the difference between the reference coordinates and the coordinates obtained by the method of RTK. Reference coordinates were obtained with GNSS static method. The quality of RTKmethod, was evaluated according to ISO 17123-8, for which we also estimated gross-errors in coordinates and removed them from the analysis. We analyzed the differences in the position quality, when we use the same network, but different GNSS receivers. We used Leica, Trimble and Javad receivers.
