Analiza kakovosti podatkov in produktov v državnem omrežju GNSS SIGNAL : magistrsko delo

Ambrožič, Valentina (author), Stopar, Bojan (mentor)

V nalogi smo obravnavali kakovost podatkov in produktov, ki jih zagotavlja državno GNSS omrežje SIGNAL. Preizkuse smo izvedli na treh deloviščih, ki so obsegala virtualno mrežo točk, z generiranimi opazovanji v obliki VRS, delovišče na Krvavcu ter delovišče na območju Avtosejma v Ljubljani. Preizkušali smo različne vplive na opazovanja in kakovost določitve koordinat točke. Zanimal nas je vpliv dolžine baznega vektorja, višinske razlike med bazno točko in roverjem, časa trajanja opazovanj in smeri baznega vektorja med bazno in novo točko. Dodatno nas je zanimal tudi vpliv nadmorske višine delovišča ter nadmorske višine VRS, na deloviščih Krvavec in Avtosejem smo analizirali tudi kakovost relativnih koordinat med točkami.

Abstract

In this thesis we dealt with the quality of data and products provided by the national GNSS network SIGNAL. The tests were carried out at three sites comprising a virtual grid of points with generated observations in the form of a VRS, a site on Krvavec and a site in the Avtosejem area in Ljubljana. We tested different influences on observations and the quality of point coordinates. We were interested in the influence of the length of the base vector, the height difference between the base point and the rover, the duration of the observations and the direction of the base vector between the base and the new point. We were additionally interested in the influence of the elevation of the site and the altitude of the VRS. At the Krvavec and Avtosejem work sites we also analyzed the quality of the relative coordinates between the points.
