ABSTRACT:
A method and apparatus are provided for predicting the position error bound in a satellite positioning system at a future time. The future position of each satellite at the future time is predicted from the trajectory data obtained from each satellite. The predicted position for each satellite and the estimated position of the satellite positioning system receiver is then used to generate a line of sight matrix at a future time, from which a position error bound value determined.
