Abstract
In a method and apparatus for selecting signals from navigation satellites, a selection is performed on signals which are directly or indirectly received from navigation satellites. Since the indirectly received satellite signals result in a false determination of position, they are suppressed. The selection is carried out for a satellite receiver, whose antenna is mounted, for example, in a vehicle in the vicinity of the rear window or the front windshield. A receiving range of the antenna is determined on the basis of the antenna location. Of the received satellite signals, those signals whose satellites are situated within the receiving range of the antenna are separated at this point. The satellites situated within the receiving range are recognized on the basis of the satellite orbits, which are stored, for example, in a storage device of the receiver.
