20.500.12556/DKUM-59357 Analiza različno dolgih statičnih GNSS opazovanj The Analysis of Different Lengths of Static GNSS Observations Namen magistrskega dela je bil primerjati opremo in metode izmere za GNSS-meritve in ugotoviti natančnost rezultatov glede na časovni interval, sprejemnik in vrsto efemeride. V prvem delu smo predstavili sistem GNSS in planiranje GNSS-izmere, ki smo ga izvedli z dvema različnima brezplačnima programoma ter primerjali z dejansko izvedbo izmere. V drugem delu je opisana obdelava GNSS-opazovanj in rezultati z analizo meritev. Statično GNSS-izmero smo izvedli s tremi različnimi sprejemniki v različnih časovnih intervalih. Meritve smo izvajali s sprejemniki Topcon Hiper Pro, Topcon Hiper V in Leica SR9500. Dobljene rezultate smo obdelali v programu Magnet Office Tools. Za vse sprejemnike smo izvedli analizo natančnosti koordinat glede na tip sprejemnika in glede na čas trajanja izmere. Za sprejemnik Topcon Hiper V smo pri 24h meritvi obdelali rezultate izmere še z rapid in final efemeridami ter preverili natančnost koordinat. Analiza glede na tip antene nam je pokazala, da novejši sprejemniki omogočajo kvalitetnejše meritve, saj sledijo tudi GLONASS-satelitom. Pri analizi časa trajanja izmere smo ugotovili, da se praviloma natančnost izboljšuje s podaljševanjem časa izmere meritve. Analiza glede na uporabo efemeride nam je pokazala, da so natančnejši rezultati pri uporabi končnih efemerid. The main purpose of this master’s thesis is the comparison of equipment and the methods used in GNSS surveying and the analysis of the accuracy of the results based on the time interval, the receiver and the type of ephemeris. In the first part, we presented the Global Navigation Satellite System (GNSS) and the planning of the GNSS surveying, which was conducted with two different programs and later on compared with the actual conducted survey. The second part describes the processing of the measurements and the results of the measurement analysis. We carried out the static GNSS survey with three different receivers in different time intervals. We performed the surveys with the following receivers: Topcon Hiper Pro, Topcon Hiper V and Leica SR9500. The obtained results were processed with the program Magnet Office Tools. We performed an accuracy analysis of the coordinates according to the type of receiver and the time of duration of the measurement for all receivers. We also processed the results of the 24h measurement of the receiver Topcon Hiper V with rapid and final ephemeris and checked the accuracy of the coordinates. The analysis based on the type of antenna used showed that newer receivers increase the quality measurements because they also follow to the Glonass satellites. The analysis of the duration of the measurements showed that accuracy increases with increase of duration. The analysis according to use of ephemeris showed that results are more accurate when using more accurate ephemeris. geodezija GNSS efemeride geometrija satelitov natančnost geodesy GNSS ephemeris satellite geometry accuracy true true false M.
