  To achieve the best performance for a Kalman filter(KF)for global navigation satellite system(GNSS)positioning,a comprehensive measurement model is required.However,the GNSS observations suffer from unmodelled errors resulting from multipath,interference,etc.These errors are difficult(even impossible)to model using parametric models.
