Denmark records GPS disruptions at record levels: Russia suspected

Denmark has recorded unprecedented GPS signal disruptions in the area of the island of Bornholm in 2026, with reasonable grounds to suspect Russia causing it.

Details: The measuring station on the Danish island of Bornholm, which records GPS disruptions, has already logged 30 instances of signal jamming and spoofing in 2026, compared with 16 throughout the whole of 2025 and 11 in 2024.

The instruments cannot identify the source of the interference, but there are reasonable grounds to suspect Russia, experts say.

"Since the start of the war in Ukraine, we have noticed a significant increase in such incidents – because GPS is widely used in military technology, including drones and missiles. So it is fairly obvious that someone, in an attempt to defend themselves, is interfering with and distorting these signals," researcher Søren Reime Larsen noted.

Jens Nielsen, captain and owner of a cargo vessel operating Baltic Sea routes, noted there had been some disruptions since February 2022, but the situation is now worsening. Whereas most disruptions had previously lasted no longer than 20 minutes, on 29 July, for example, there was no adequate signal for an entire day in the zone between Gdańsk and Gotland.

The worst problems occur in the south-eastern part of the Baltic Sea, he said.

Background:

• Finland warned in May of frequent GPS disruptions in the area of the Åland Islands, whereas problems had previously been confined to the Gulf of Finland.
• Sweden reported a sharp increase in GPS interference over the Baltic Sea in 2025, which affected civilian aviation.
