Abstract
V diplomski nalogi smo preverili vpliv oddaljenosti od stalne postaje na točnost določitve položaja pri uporabi statičnih in kinematičnih metod izmere GNSS. Izmero smo izvajali na šestih točkah v okolici Ljubljane in Vrhnike na oddaljenostih od 5 do 25 kilometrov od stalne postaje v Ljubljani. Položaje izbranih točk smo določili po metodi hitre statične izmere ter RTK-izmere, pri čemer smo za referenčno stojišče uporabili virtualno točko VRS v bližini delovišča ter stalno postajo GSR1 v Ljubljani. Pri obdelavi opazovanj GNSS po metodi hitre statike smo kot referenčno stojišče uporabili VRS, ki je bil lociran na različnih oddaljenostih od delovišča. Pri hitri statični metodi izmere smo preverjali tudi pravilo časovnega trajanja izvedbe opazovanj: trajanje opazovanj = 10 min + 1 min · b, pri čemer je b oddaljenost od referenčne postaje. Ugotovili smo, da je pri hitri statični metodi izmere čas opazovanj potrebno podaljšati, če smo bolj oddaljeni od referenčnega stojišča.

Title:Horizontal distance from continuously working reference GNSS station influence on the position accuracy
Abstract:
The aim of our thesis was to check the effect of distance from the continuously working GNSS reference station on the accuracy of positioning when using static and kinematic GNSS surveying methods. Field measurements were carried out at six points in the area near Ljubljana and Vrhnika at distances from 5 to 25 kilometres from the GNSS continuously working reference station in Ljubljana. Coordinates of selected points were determined using rapid static and RTK measuring method. In RTK method a virtual reference station VRS created near the worksite and permanent station GSR1 were used as reference stations. When processing the rapid static observations VRS located at different distances from the worksite was used as the reference. With rapid static we also examined the rule: the observation time = 10 min + 1 min · b, trajanje where b was the distance from the reference station. We found out that the observation time needs to be longer if we are further away from the reference station.
