Abstract: In a method for providing route-specific information in a vehicle, the present location of the vehicle is determined in the vehicle. A plurality of information data is received in the vehicle that in each case associate at least one route situation with locations or location areas. The plurality of information data is related in each case to the determined location of the vehicle, and there are determined the information data that comply with predefined association criteria. A device, a vehicle and a traffic information system comprise corresponding features. An embodiment of the invention improves and extends the technical possibilities of informing a vehicle driver about route situations.

Abstract: A method and apparatus for altering the coordinates obtained by satellite navigation in a receiving system which fixes an incorrect position, instead of a true position, within a given three-dimensional zone. In connection with altered coordinates, additional navigational information such as course and speed can also be influenced. Specifically, signals are received from a site and re-emitted in a suitable way so that a navigation receiver determines the position of the receiving site within the three-dimensional zone covered by the emission. This approach is superior to noise-blanketing countermeasures (such as carrier or noise interference) in that precise but untrue coordinates are determined in the navigation receiver, without this incorrectness being immediately recognized.
