In this master thesis we analysed coordinate quality determined with GNSS-RTK surveying in adverse conditions. To analyse the impact of adverse conditions on the results of the GNSS-RTK measurements, we set up a worksite, determined the reference coordinates of geodetic points and performed GNSS-RTK measurements with five different GNSS receivers on a basis of two GNSS permanent networks, SIGNAL and SmartNet. The results obtained were evaluated according to different quality criteria. The conclusion of the thesis is that in adverse conditions we did not achieve the required a few centimeters accuracy level and that the quality of the coordinates determined is independent of the used GNSS permanent network.
