For the fourth consecutive year, Jammertest will take place in Bleik on Andøya, Norway, with applications now open until March 15, 2025. This event serves as a critical platform for industry and equipment manufacturers to test their systems against jamming and spoofing attacks, identify vulnerabilities and develop more resilient solutions. It attracts participants from diverse sectors, including the global automotive and security industries, telecommunications, academia and government authorities.

The event’s importance is underscored by the growing reliance of civilian services on satellite communications. Essential societal functions — such as transportation, emergency services, electronic communication, financial systems, and power supply — depend on accurate satellite-based positioning and timing. However, incidents of signal interference have highlighted vulnerabilities. For example, rescue helicopters in Norway have faced landing difficulties due to disrupted signals, and airports have been affected by illegal jammers. Airlines have also reported spoofing activity. According to the Norwegian Communications Authority, GNSS interference is an escalating concern that demands ongoing testing and innovation.

Jamming refers to the deliberate disruption of signals such as GPS or radio frequencies, while spoofing involves transmitting false signals to deceive receivers. Both tactics pose significant risks to civilian infrastructure. The Jammertest provides a unique opportunity for participants to evaluate their equipment under real-world conditions at Andøya’s remote location. This setting allows for “open air” testing without risking disruptions to civilian infrastructure or air traffic control systems — an advantage not feasible in densely populated areas.

Andøya’s geography makes it an ideal site for these trials. Surrounded by mountains and isolated from major population centers, it enables high-power signal testing while minimizing societal impact. Participants receive direct feedback on how their systems perform under controlled interference scenarios.

About Jammertest

Jammertest is recognized as the world’s largest open arena for testing resilience against jamming and spoofing attacks. It is organized in collaboration with several Norwegian authorities, including the Norwegian Public Roads Administration, Norwegian Communications Authority, Norwegian Defense Research Establishment, Norwegian Metrology Service, Norwegian Space Agency, Norwegian Mapping Authority, and Testnor.

This year’s event is scheduled from Sept. 15-19, 2025.
