Experts from the Gdańsk University of Technology, the Maritime University of Gdynia, and the Institute of Telecommunications have for months been indicating that the main sources of interference and signal falsification (spoofing) are located in the [Russia-controlled] Kaliningrad region.

Poland is one of the most exposed countries to the problem, as a significant part of its territory, especially at cruising altitude, falls within range of jamming systems from the area.

Lithuania reported in 2026 that spoofing infrastructure in Kaliningrad had been significantly expanded, with the number of antennas increasing from just a few at the start of 2025 to several dozen. This reportedly makes it possible to falsify signals over distances of up to 450 km, meaning it could potentially cover much of Poland, the Baltic states, and parts of the Nordic region.

The Institute of Telecommunications warned people against relying solely on their phone’s maps. It is instead advised that people use traditional navigation and orientation methods where possible, or to download maps for offline use in advance.

In the longer term, Poland is developing its own monitoring systems, including a portal based on the ASG-EUPOS network and a planned network of sensors run by the Polish Space Agency.

Since Russia launched its full-scale invasion of Ukraine in February 2022, dozens of similar incidents have been recorded in Europe, particularly in the Baltic, Nordic, and Black Sea regions.

Western officials and experts have repeatedly pointed to Russia, which claims the actions are taken to defend against Ukrainian drones. But Baltic and Scandinavian countries stress that the range and intensity of the interference go far beyond Russia’s borders and amount to a systematic provocation.
