International technology suppliers meet in Norway to test how modern GPS/GNSS technology withstands Jamming, Spoofing and Meaconing attacks.
Helix Geospace participated in this year’s Jammertest, taking place in Andøya, Norway, from September 9-13th 2024. Participants from 90 organisations and 20 countries gathered to test their technology’s resilience against interference, jamming and spoofing threats. This event offers a unique opportunity to evaluate our innovative resilient GNSS CRPx solution in real-world conditions.
As the largest jamming and spoofing test globally, Jammertest 2024 is supported by key Norwegian authorities, including the Public Roads Administration, Communications Authority, Defence Research Establishment, Metrology Service, and Space Agency. It provides a controlled environment where GNSS antennas and receivers are rigorously tested for their ability to resist intentional signal interference. The event provides a wide range of tests, including high-power jamming, low-power jamming, time spoofing, position spoofing, and meaconing, all in real environments.
The low-power jammers used in the tests include a mix of L1-only, L1&L2, and L1&L2&L5/E6 jammers, all operating across wide frequency bands. Most employ sweep modulation, with one utilising frequency hopping. These jammers range from inexpensive “eBay jammers” to military-grade handheld devices.
For the high-power jammer, three types of modulation were used: an unmodulated carrier wave (CW) for GPS L1, a sweep signal (“chirp”), and a PRN signal (modulated carrier wave with the C/A code from GPS satellite #1, but without the navigation message). Jamming occurred using various modulation and frequency band combinations. The jamming was initiated from an elevated mountain location towards Bleik.
For Helix Geospace, this was a crucial step in validating the robustness of our technology, ensuring our antennas maintain resilient Position, Navigation, and Timing (PNT) even in challenging conditions. This aligns with our commitment to providing secure and reliable solutions for industries that depend on uninterrupted GNSS services.
By participating, we were able to strengthen the integrity of global PNT systems and contribute to the development of solutions that can withstand growing interference threats.
