Problems and interference with geolocation systems (GPS_ encountered over the weekend more than 1,600 European aircraft flying over the Baltic in eastern Europe.

The interference lasted about 48 hours and affected the GPS of 1,614 planesmany of which were civilian, full of passengers.

Aircraft flying over several NATO member states in eastern Europethey also reported interfering with their GPS signals.

Most interceptions took place within Polish airspacebut also on planes flying within the FIR of Germany, Denmark, Sweden, Lithuania and Latvia.

According to Newsweek the increase in interference can be largely attributed to the Russian enclave of Kaliningradlocated between NATO members Poland and Lithuania, serving as a base for one of Russia’s most important naval fleets.

There Moscow is believed to possess significant means of electronic warfare.

“The Russian armed forces have a wide range of military equipment for GNSS (Global Navigation Satellite Systems) jamming, including jamming and spoofing, at various distances, durations and intensities”said a Lithuanian armed forces source.

Interference or spoofing of Global Positioning System (GPS) and wider Global Navigation Satellite Systems (GNSS) signals can confuse manned or unmanned aircraft or make their navigation systems think they are in a different location , with potentially tragic results.
