Method for detecting global positioning system signals produced in unauthorized manner, involves receiving global positioning system signals for determining routing by global positioning system receiving unit

摘要

The method involves receiving Global positioning systemsignals (S1-S4) for determining the routing (11) by a global positioning system receiving unit (3). The routing is computed on the basis of the received global positioning system signals. The routing is determined using navigation sensors (6) with a sensor navigation system (5) in a redundant manner and the routing is transmitted to a comparison unit (8). The resizing and discontinuity of the zero shifts are monitored by a comparison unit. An independent claim is also included for a device for detecting global positioning system signals produced in an unauthorized manner in a vehicle.
