diplomska naloga
Abstract
Diploma naloga obravnava kakovost določitve 3D položajev točk z uporabo GNSS RTK
metode izmere za primer, da različnim točkam položaje določamo v istem trenutku. Cilj naloge
je pridobiti izkušnje o možnosti izboljšave relativne natančnosti položajev točk, če izberemo
način, da točkam določamo položaj z GNSS RTK-metodo istočasno. Za to potrebujemo več
operaterjev, ki istočasno na različnih točkah določajo položaj z RTK-metodo izmere. Opravljeni
test sestavljajo nizi pridobljenih koordinat, ki se dodatno nanašajo na različna trajanja določitve
koordinat z RTK-metodo izmere. Za namen poizkusa smo trem točkam najprej določili bolj
kakovostne 3D coordinate s statično GNSS metodo izmere. Na istih točkah smo nadalje
določili položaje z RTK metodo izmere in sicer najprej istočasno na vseh točkah, nadalje pa v
različnih trenutkih na posameznih točkah. Koordinate iz RTK-metode izmere smo najprej
primerjali s koordinatami iz statične metode izmere. Sledila je statistična primerjava vzorcev
koordinat z različnimi izvedbami RTK-metode izmere (različni trenutki opazovanj, različna
trajanja opazovanj). Iz opravljenih testov lahko zaključimo, da istočasna določitev koordinat z
RTK-metodo izmere na različnih točkah vodi do boljše relativne natančnosti koordinat med
točkami. Druga ugotovitev pa je, da daljša izvedba opazovanj pri RTK-metodi izmere void do
bolj kakovostne določitve položajev točk.

Setting up of coordinate basis with GNSS on the basis of simultaneous RTK-measurements |
Secondary abstract: |
The graduation thesis deals with the quality estimation of simultaneous acquisition of 3D
coordinates using GNSS RTK method. The aim is to acquire the knowledge of the possibility
of the internal network quality improvement by RTK-measurements performed at different sites
at the same time. For this purpose we need several operators at different sites, which are
synchronized in timings of measurements.The test consists from a set of several
measurements acquired by RTK-method with different timing and different occupation
durations. For the experimental tests the network of three points has been established and
determined by a static GNSS method. On the same locations coordinates were further
determined using simultaneous measurements of multiple receivers as well as by successive
measurements with different timings of coordinate’s determination. RTK coordinates were
compared first with coordinates from a static determination. Second comparison of coordinates
of simultaneous and successive determination as well as coordinates with different occupation
durations was performed. From the experimental test we can conclude simultaneous RTKmeasurements,
if possible, enable better internal precision achievement. Second conclusion
is that longer occupation duration leads to the coordinates of a better quality. |
