DETECTION OF GNSS NAVIGATION DATA MANIPULATION BASED ON GNSS SYSTEM TIME DIFFERENCES

It is inter-alia disclosed a method performed by a mobile device, the method comprising:- receiving at least one global navigation satellite system, GNSS, signal related to a first GNSS system time;- determining at least one system time difference between the first GNSS system time and a reference t...

Beschreibung
Zusammenfassung:	It is inter-alia disclosed a method performed by a mobile device, the method comprising:- receiving at least one global navigation satellite system, GNSS, signal related to a first GNSS system time;- determining at least one system time difference between the first GNSS system time and a reference time at least partially based on said at least one GNSS signal;- obtaining at least one reference system time difference; and- determining, at least partially based on said at least one system time difference and said at least one reference system time difference, whether or not said at least one GNSS signal is potentially manipulated.
