Accuracy Assessment of RTK GNSS based Positioning Systems for Automated Driving

High accuracy positioning systems are crucial for automated driving. Real-Time Kinematic (RTK) positioning is widely used in high-precision positioning and navigation applications, and can also be used in automated driving use cases. Little public information is available, however, on how the accuracy deteriorates as a function of the distance between the base station and the vehicle. This paper presents a practical approach and experimental results to characterize accuracy effects from increasing RTK operating range.
