Interference sources like In-Car Jammers block GNSS signal reception in their vicinity and degrade GNSS performance, proportional to the distance, over a wide area. As novel and innovative ITS and vehicular communication rely on a precise and reliable position determination, the threat of interference should not be underestimated. A system to protect the infrastructure and their revenue streams needs to be established. The GNSS community is well aware of the interference threat and working on solutions. The work presented in this paper suggests an enhancement of automotive receivers in a way that interference can be detected and reported to a back-end by means of vehicular communication. This enables the notification of affected vehicles and the localization of the interference source.
