Characterisation Of Multipath-Caused Commercial- Grade GPS Positioning Error In Intelligent Transport Systems (ITS)

The constant increase in the use of Global Navigation Satellite Systems (GNSS) in different technical and economic areas requires the determination of the position with the required accuracy for each individual application. In a user environment where the so called multipaths when receiving the signal from the satellite comes to their effect on the error of determining the position. In this paper, we present the influence of multiple paths on the position determination error in intelligent transport systems using the Autoregressive Model (AR). The influence of multipath on position determination error shows significant deviation from normal distribution and requires more complex AR models or introduction of complex Autoregressive Moving Average (ARMA) models or stochastic models.
