The European Union’s STRIKE3 project reported at the US PNT Advisory Board meeting last week that their study of GPS/GNSS jamming in Europe and elsewhere has shown that jammers are evolving to become more sophisticated and prevalent.
The results of measurements at eight national airports for 30 day periods was shown as an example of their work. Almost 21,000 interference events were detected. While only 1,141 were assessed to be deliberate interference, 4,243 events resulted in GPS/GNSS service being denied.
