Our expert in a debate on GNSS signal interference

14.11.2025

On 13 November 2025, a debate titled "Assessing Preparedness to Combat Jamming and Spoofing: Business and Regulatory Perspectives” took place in Brussels. The event was organized by the Permanent Representation of Lithuania to the EU and the Lithuanian Ministry of Transport and Communications. Among the invited experts from several European countries was Dr. Krzysztof Bronk from the Gdańsk branch of the National Institute of Telecommunications.

Dr. Krzysztof Bronk among the participants of the debate "Assessing Preparedness to Combat Jamming and Spoofing: Business and Regulatory Perspectives” in Brussels.

The experts discussed how Europe should address the steadily increasing number of disruptions to Global Navigation Satellite System (GNSS) signals in the Baltic Sea region. Deliberate interference caused by Russia is negatively affecting air traffic, maritime navigation, and all users of devices relying on satellite-based navigation systems.

Dr. Krzysztof Bronk, Head of the Wireless Systems and Networks Department at the National Institute of Telecommunications in Gdańsk, took part in the panel discussing real-world examples of the negative impact of such disturbances and countermeasures applied in various sectors and transport corridors. The Gdańsk branch of the Institute has for several years specialized in GNSS interference issues and is developing solutions to detect and mitigate them.

Dr. Bronk spoke, among other topics, about the RTGMS project carried out jointly with the Head Office of Geodesy and Cartography, which involves the creation of an interference monitoring system, as well as about alternative terrestrial radionavigation systems – such as VDES R-mode, developed within the European ORMOBASS project. He also mentioned Galileo PRS (Public Regulated Service) as a solution significantly more resistant to jamming and spoofing. The Gdańsk branch is involved in the newly launched research project Pursuit-X, which aims to verify the reliability of this service.

Krzysztof Bronk shared Polish experiences and best practices in detecting and countering GNSS interference. Compared with other countries, Poland has extensive expertise in this field, and the other participants of the conference were very interested in our achievements. The role of Poland and the National Institute of Telecommunications was strongly emphasized during this important meeting.
