Due to interference, Finnish airports have begun using radio navigation systems.

According to Finnish authorities, Russia is jamming the Global Navigation Satellite System (GNSS) and the Global Positioning System (GPS) in the Baltic Sea region. This is allegedly being done to prevent drone strikes on strategic sites in the area.

Reports indicate that since September of this year, airports in the cities of Joensuu and Savonlinna, located nearly an hour's drive from the Russian border, have begun using upgraded radio navigation equipment. The airport in Lappeenranta also plans to implement this in the near future. This equipment does not rely on GPS signals.

The decision to install radio technical equipment for distance measurement was made after two domestic flights operated by Finnair to Joensuu were canceled this summer due to GPS interference. In the spring, the carrier suspended some flights to Tartu for a month for the same reason.

In April 2024, The Sun wrote that thousands of British flights had been subjected to GPS jamming. It is believed that this was carried out by Russia. Ryanair reported GPS interference on over 2,300 of its flights in the airspace of the Baltic region, while Wizz Air reported nearly 1,400, British Airways 82, and EasyJet four.

The disruptions in GPS operations have increased since the onset of the war in Ukraine. Airlines report a significant number of incidents in the Baltic Sea area, particularly over the Kaliningrad region, as well as over the Black and Caspian Seas and in the eastern Mediterranean.
