Distance-Based Send-on-Delta to test the Accuracy of GNSS receivers

GNSS accuracy is an important parameter to track vehicle movements in the Earth surface. This paper investigates a new way to dynamically determine the GNSS accuracy based on the Linear-Predicted Send-on-Delta strategy. The proposed method calculates the average deviation of the position measured by a GNSS sensor for a vehicle that moves linearly with constant velocity. Results show that the measured accuracy, named in this work as position-tolerance, is much more precise than the accuracy given by the GNSS sensors, and could be used to improve new position tracking methods.
