Metoda Precise Point Positioning (PPP) določitve položaja v GNSS : diplomska naloga

Šulin, Lan (author), Stopar, Bojan (mentor), Sterle, Oskar (comentor)

V diplomski nalogi smo obravnavali metodo Precise Point Positioning (PPP). Predstavljene so teoretične osnove metode, z vplivi in popravki, ki jih je potrebno upoštevati. Izvedli smo raziskavo zanesljivosti metode z uporabo prosto dostopnega kanadskega spletnega ponudnika CSRS-PPP. Uporabili smo celodnevna opazovanja treh stalnih GNSS-postaj omrežja SIGNAL (CELJ, IDRI in SLOG). Za vse tri postaje smo izvedli PPP obdelavo in analizo rezultatov za opazovanja med 10. in 16. marcem 2025. Opazovanja postaje v Slovenj Gradcu (SLOG) smo še globlje analizirali, tako da smo RINEX-datoteke razrezali na različno dolge krajše časovne intervale (od 15 min do 24 ur). Cilj naloge je bil ugotoviti, kako krajšanje trajanja opazovanj korelira z natančnostjo rezultatov.

• Title: Precise Point Positioning (PPP) method of determining position in GNSS : graduation thesis

Abstract

In this graduation thesis we studied the Precise Point Positioning (PPP) method. The theoretical foundations are presented, including the effects and corrections that need to be considered. We carried out a reliability analysis of the method using the free Canadian online service CSRS-PPP. We used fullday observations from three permanent GNSS stations of the SIGNAL network (CELJ, IDRI, and SLOG). For all three stations, PPP processing and result analysis were performed for observations between March 10 and March 16, 2025. The observations of the station in Slovenj Gradec were subject to a more in-depth analysis by splitting the RINEX files into shorter time intervals of different lengths (ranging from 15 minutes to 24 hours). The aim of the thesis was to determine how shortening the duration of the observations correlates with the accuracy of the results.
