A satellite navigation method for a mobile station which is installed, in particular, in a traffic route-guided vehicle. Several reference marks are installed along the traffic route at predetermined distances from one another, with the geographic positions of the reference marks being known or supplied to a mobile station passing a reference mark. The reference marks are detected by a reading device which is disposed in the mobile station. At the location of a reference mark and at the moment of its detection, the actual ranges and the pseudoranges from all satellites that are relevant for navigation are determined simultaneously and are compared. The measuring error change of the satellite navigation or the adjustment of the correction value maybe carried out with the aid of a velocity indicator and a route map mounted on the mobile station. From these, correction values are derived which are used for a pseudorange correction outside of the range of the reference marks. The method permits a (navigational) precision corresponding to a differential navigation method without necessitating communication with a stationary reference station.
