Sekundarni naslov: Development and analysis of methods for GPS carrier phase double differences forming
Sekundarni povzetek: In this thesis various methods of reference satellite determination, used for carrier phase double differences forming are tested and analyzed. First, the theoretic introduction is made to enlighten the scope of our research. Hereinafter our research on finding and programming the optimal method for reference satellite determination using Dijkstra’s algorithm is presented. The method is based on theoretical assumptions found in literature. Whole research process and programs made to implement our method are described in details. In the second part of the thesis we perform a test of newly developed and existing methods for reference satellite determination using GPS data processing for baseline estimation. A set of observations from permanent stations that form three baselines with different lengths is chosen in order to test and analyze the effect of individual methods on different baselines. Furthermore, we test how limiting of reference satellite duration and using different altitude limits for reference satellite affect the results of GPS data processing. A comparison is made between developed and existing method, both using different altitude limits for reference satellite. We finish with analysis of results and final conclusions.

Povzetek (ePrints): V diplomski nalogi smo testirali in analizirali različne metode izbire referenčnega satelita, ki se uporablja pri sestavi dvojnih faznih razlik. Nalogo začnemo s teoretičnim uvodom, katerega namen je predstaviti področja, na katera seže naše raziskovanje. V nadaljevanju je podrobno opisan postopek iskanja in razvijanja programske kode za optimalno metodo iskanja referenčnega satelita. Metoda pri svojem delovanju uporablja Dijkstrov algoritem in temelji na teoretičnih izhodiščih, podanih v literaturi. V drugem delu diplomske naloge smo z uporabo obdelave GPS-opazovanj za oceno baznega vektorja testirali razvito in obstoječo metodo za izbiro referenčnega satelita. Izbrali smo testni niz opazovanj permanentnih postaj, ki tvorijo tri vektorje različnih dolžin. S tem smo omogočili analizo, kako posamezne metode delujejo na vektorjih z različnimi dolžinami. Poleg tega smo testirali, kako časovno omejevane trajanja posameznega referenčnega satelita in različne omejitve višinskega kota za referenčni satelit vplivajo na rezultate obdelave GPS-opazovanj. Pri obdelavi z različnimi omejitvami višinskega kota za referenčni satelit smo uporabili tako obstoječo, kot tudi novo razvito metodo in ju primerjali. Zaključimo z analizo vseh rezultatov in podamo sklepne ugotovitve.
