Claim 18:
19. A method comprising:
receiving a global navigation satellite system (GNSS) signal for a moving vehicle;
obtaining a position estimation of the vehicle by inputting values of observable characteristics into an artificial intelligence (AI)-based model and receiving the position estimation as an output from the AI-based model, the AI-based model applying different coefficients to the values of the observable characteristics to output the position estimation;
calculating an error between a location derived from the GNSS signal that is received and the position estimation obtained from the AI-based model;
calculating an uncertainty in the location derived from the GNSS signal based on the error that is calculated; and
calculating one or more changes to the one or more of the coefficients applied to the observable characteristics in the AI-based model by inputting the uncertainty in the location to an unscented Kalman filter.
