The dense RTK network, TAPAS is a research and development platform in Aarhus set up as a part of the Danish implementation of Galileo. The expectation to TAPAS is a standard deviation of 1 cm horizontally and vertically.
This project examines the effect Galileo and TAPAS have on the precision. The data collection is performed in three different environments; open rural, open urban and dense urban. In the open rural environment Galileo has no significant effect on the precision, and TAPAS is significantly less precise than Leica SmartNet. In the open urban environment, Galileo has significant effect on the precision, TAPAS has no significant effect. In the dense urban environment, Galileo has significant effect for E, while TAPAS has significant effect on the E- and U-coordinate.
There is a systematic deviation between the mean coordinates between Leica SmartNet and TAPAS of 1.5, 0.7 and 10.6 cm for E, N and U. It can not be concluded that TAPAS gives more precise RTK-measurements than Leica SmartNet. Galileo has none or positive effect on the precision.
