V diplomski nalogi smo analizirali natančnost določitve položaja z uporabo nizkocenovnih enofrekvenčnih GNSS sprejemnikov za potrebe v navigaciji. Meritve smo opravili z dvema nizkocenovnima enofrekvenčnima sprejemnikoma, za primerjavo pa smo imeli tudi meritve geodetskega dvofrekvenčnega sprejemnika, kjer smo uporabili samo valovanje L1. Delovanje sprejemnikov smo preizkusili v relativnem načinu, z baznimi vektorji pri kratkih razdaljah. Uporabili smo dve metodi, statično in kinematično, saj smo hoteli preizkusiti, kako bi se instrumenti obnesli pri navigacijskih nalogah, kjer bi potrebovali nekaj centimetrsko natančnost.In this diploma thesis the accuracy of the position determination through low-cost single-frequency GNSS receivers in terms of navigation has been analysed. The measurements have been carried out by two low-cost single-frequency GNSS receivers and (later) compared to the measurements made by a geodetic dual-frequency GNSS receiver, where only the L1 carrier has been taken into account. The receivers were tested in relative positioning mode, using short baseline vectors. The measurements have been processed in static and kinematic mode to see, how efficient the instruments would be in tackling navigation tasks that require an accuracy of a few centimetres
