Abstract:
1. A method for determining, via a sensor network, a position of a GNSS receiver arranged in a motor vehicle that is intentionally is impaired in a targeted manner by an interference source, the sensor network including a plurality of predetermined traffic route points that have at least one sensor structured and arranged detecting a presence of the interference source, the method comprising: detecting, as the motor vehicle passes one of the plurality of predetermined traffic route points, at least one of an interference signal emitted by the interference source and a received signal of the GNSS receiver impaired by the interference source by the at least one sensor of the one traffic route point; processing the detected signals to establish whether the interference source is present in the passing motor vehicle; and when the presence of the interference source is established, generating information that signals at least a location of the one traffic route point and the interference source in the motor vehicle; wherein a position of the motor vehicle is determined from the location of the traffic route point.
