The organizers of Jammertest are excited to announce that the Jammertest 2025, once again, has gained record-high interest from around the world, with a massive number of applicants for this year’s event.
We are happy to welcome all invited organizations to Andøya 15–19 September 2025.
Security for PNT
Our dependency on satellite technology is higher than ever before. Critical infrastructure and essential services are reliant on precise position, navigation and time accuracy. Unfortunately, at the same time as our dependency has increased, so has the occurrence of jamming and spoofing attacks. However, ongoing research in a unique collaborative event offers promising solutions to improve our security.
The Jammertest is a collaborative effort to strengthen digital infrastructure and protect the critical services that support our modern societies. Jammertest is organized by the Norwegian Public Roads Administration, Norwegian Communications Authority, Norwegian Defence Research Establishment, Norwegian Metrology Service, Norwegian Space Agency, Norwegian Mapping Authority, Avinor and Testnor, with the aim of advancing Positioning, Navigation, and Timing (PNT) security.
A Unique Location for Robustness Testing
At Jammertest, participants are given the opportunity to subject their systems and products to thorough examination. System owners, suppliers and end-users are gathered to explore vulnerabilities. We do this in our three unique test areas, both through simple and sophisticated jamming and spoofing. During the 2024 test week, over 250 comprehensive tests were conducted, exploring various aspects such as sensor fusion, radio frequency interference (RFI) countermeasures, and combinations of GNSS (Global Navigation Satellite Systems) with other PNT sources. The insights gained from these tests contribute directly to enhancing the robustness and reliability of PNT systems worldwide.
Importance and Impact
This year marks the fourth consecutive Jammertest held on Andøya, an event that continues to draw significant attention from the PNT industry. Stakeholders across industry, government, and academia recognize the critical need for testing to address today’s evolving threats.
The 2025 edition of Jammertest, scheduled for September, has attracted record interest, with over 150 organizations from 24 countries applying to participate. The test has limited capacity and invited organizations has been selected based on considerations of Norwegian national interest. We encourage those who were not selected this year to apply again for future events.
