Uporaba satelitskih sistemov GPS, GLONASS, Galileo in Beidou v geodetski izmeri : diplomska naloga

Vesel, Matej (author), Stopar, Bojan (mentor), Sterle, Oskar (co-mentor)

Danes imamo geodeti pri izmeri GNSS na voljo več različnih satelitskih sistemov. V tej nalogi na kratko predstavimo posamezne sisteme, nato pa preučimo, kako uporaba posameznih ali kombinacij sistemov vpliva na določitev položaja. To storimo z analizo opazovanj treh stalno delujočih postaj GNSS za različno dolge časovne nize. Analiziramo podatke kot so število vidnih satelitov, velikost faktorjev DOP, odstopanja izračunanih koordinat od referenčnih in standardni odkloni izračunanih koordinat. Na podlagi analiz sklepamo, kakšen učinek imajo uporabljeni sistemi GNSS na te podatke.

Abstract

There are multiple different GNSS systems available for use in surveying today. In this thesis we present these systems in short, then study the effects of using one or multiple GNSS systems on positioning. We do that by analysing the observations of three permanently operating GNSS stations for intervals of various lengths. We analyse data such as the number of visible satellites, DOP factor values, the differences between calculated and reference coordinates and the standard deviations of calculated coordinates. Based on these analyses, we make conclusions regarding the effect of used GNSS systems on this data.
