Abstract
Method for the transmission of navigation data to user terminals of a satellite navigation system composed of navigation satellites and pseudolites. The method includes transmitting positional information for at least one of the pseudolites, as part of the navigation data, without the use of separate channels or protocols for the transmission of the positional information for the at least one pseudolite. The positional information is transmitted in the form of a model of a pseudolite trajectory in a reference coordinate system which the model accounts for orbit-divergent motions of the at least one pseudolite, and the positional information for the at least on pseudolite forms a part of the navigation data.
