Performance Analysis of the RTK Technique in an Urban Environment

Abstract

This study investigates the RTK achievable accuracy and repeatability under different satellite configurations and site conditions in an urban environment. Impact of the RTK data latency is quantified. Results show that the RTK is more stable for the horizontal coordinates than the height, and data latency generates errors of a few millimeters. Positioning accuracy on the cm level can be routinely achieved when observing sufficient number of satellites.
