Abstract
V diplomski nalogi je predstavljen postopek vzpostavitve geodetske mreže točk, ki je namenjena istočasnemu preizkusu treh instrumentov RTK-GNSS na višjih nadmorskih višinah. Mreža je vzpostavljena na območju Planine Jezerca na Krvavcu, da so referenčne bazne postaje državnega omrežja stalnih postaj GNSS, SIGNAL, veliko nižje, kot je samo delovišče. Mreža šestih točk je bila vzpostavljena s klasično metodo izmere, zatem smo koordinate določili z večkratnimi ponovitvami RTK-GNSS metode. Pri pripravi terestričnih meritev za nadaljnjo izravnavo smo ocenili vpliv pogreškov merjenih meteoroloških in drugih parametrov na reducirane vrednosti dolžin. Izračun vplivov pogreškov je pokazal, da na kakovost rezultatov največ vplivajo spremembe: zračnega tlaka, temperature, merjene zenitne razdalje in dolžine Sr.

Title:Establishing a network of points to test RTK-GNSS instruments at bigger altitudes
Abstract:
The graduation thesis presents a conceptual model of the establishment of the geodetic network, which could be used for simultaneous testing of three different instruments GNSS-RTK. The geodetic network was established in the mountainous area of Jezerca on Krvavec, since the continuously working reference stations GNSS of the national network SIGNAL are located in much lower altitudes. The network comprises six points, established by the classic terrestrial measurements. Moreover, their coordinates were determined globally by several repetitions of the GNSS-RTK method. For the terrestrial measurements, we evaluated influences of meteorological and other parameters on the reduction of the distances. The simulations showed that the greatest influences were due to barometric pressure, temperature as well as the measured zenith distance and distance Sr.

Keywords:classic method measurements, method measurements GNSS, distance reduction, the influence of individual quantities, adjustment network
