Vertical component quality comparison of GPS RTK method in combination with laser system vs. conventional methods for height determination
For the most common geodetic tasks such as surveying, staking out and monitoring, GPS RTK method has been in many cases limited by its vertical measuring quality. Combining laser system with GNSS RTK system enables the increase of vertical accuracy of measurement to a millimetre level. In this paper testing the mentioned system (developed by Topocon i.e. mmGPS) and its comparison with conventional methods for height determination will be presented. Testing the vertical accuracy using different measuring methods has been done on the calibration baseline of the Faculty of Geodesy in Zagreb. Heights were determined using four different measuring methods ; differential levelling, trigonometric levelling, GPS RTK and GPS RTK method in combination with laser system. The authors of the paper tried to examine whether it is possible to achieve higher accuracy of vertical component when GNSS RTK system is combined with laser system. The results of height comparison, analysis of vertical accuracy and precision of measuring methods is presented in this paper. The statistical tests were used to examine whether there are significant differences in accuracies obtained by different measuring methods.
