Comparison of deformation analyses performed on the basis of GNSS observations using single-frequency and double-frequency measurement receivers

摘要

The given article addresses 2D processing of a deformation network measured using Global Navigation Satellite Systems in partof the Dargovskych Hrdinov housing estate. In order to perform deformation analyses and their comparison, two stages of measurementwere performed using single-frequency as well as double-frequency measurement receivers. Experimental measurements were takenusing the static method by permanent observation at selected observed and reference points of the deformation network. The geodeticnetwork in both stages was processed using the Gauss-Markov model with full rank and using the least square method whilstobservations were tested and the results of performed deformation analyses were graphically visualised using relative confidenceellipses on the basis of a positional and altitudinal plan.
