Russia's attempts to jam GPS signals, following a series of drone attacks, have interfered with the navigation system in Estonia. According to Bloomberg, citing a letter from the Estonian Department of Transport, the source of interference is believed to be located in the Leningrad region, which borders Estonia and Finland.
Due to interference with GPS, pilots of aircraft flying to the Baltic countries and Finland have to use alternative methods of navigation. Ground traffic has not yet been affected, according to a letter from Estonian officials. The Estonian authorities believe that the jamming of GPS signals is one of the measures by which Russia is trying to protect strategic objects on its territory.
The Finnish Air Traffic Authority confirmed that Finnish pilots are using alternative navigation systems and commercial flights are flying on schedule.
On the night of May 3, two drones exploded on the territory of the Kremlin. The Russian authorities have accused Ukraine of trying to attack the residence of Vladimir Putin. After that, reports of malfunctions in the GPS began to arrive from Moscow. In particular, as the press service of the Public Council for Taxi Development told The Insider, taxi drivers complained about interference.
