Intentional and unintentional interference are recognized as major threats to users of GNSS-based

positioning. Existing detection and mitigation methods lack the adjustability to deal with the ever-
increasing complexity in GNSS interference attacks. Our ANTIFERENCE system will employ artificial

intelligence to detect both known and never-before-observed interferences. It operates the way
antivirus software works, by detecting threats based on the “fingerprints” of incoming signals. These
fingerprints are stored in a database, together with the appropriate countermeasures. The database
can be shared among different receivers to further improve effectiveness.
