Be ready to see us at Jammertest 2025, the world’s largest open-air event for testing the resilience of positioning and navigation systems against jamming and spoofing.
From September 15 to 19, our team joined over 400 participants in Bleik and Andøya, Norway, for the world’s largest GNSS jamming and spoofing resilience event. To reach the location, they drove 3,400 kilometers—40 hours of driving across six countries. Now that Jammertest 2025 has concluded, we’re proud to share the significant results of our final test days and how they strengthen trust in SBG Systems.
Key testing highlights

- Multidirectional jamming & spoofing: We evaluated passive and CRPA AntiJamming antennas under challenging, real-world interference.
- Spoofing round two: We conducted a second series of mobile spoofing tests, adjusting configurations for even higher resilience in GNSS-denied environments.
- Additional driving tests: Our team drove near and within jammed zones to push system capabilities further.
- High-latitude gyrocompassing: Norway’s northern location enabled us to trial our new gyrocompassing unit under extreme geographic conditions.
What we collected and learned at Jammertest
This participation is a testament to our ongoing commitment to robust, trustworthy technologies.
Our products already operate reliably in adverse field conditions. The demanding Jammertest setting provides a structured environment for evaluation. Thank to that, we collected several terabytes of data during these tests. This data helps us enhance the resilience of our solutions. It also strengthens the overall robustness of our technology.

We see this as a rigorous technical test but also as a collective achievement for our organization. It highlights unity, preparation, and innovation at every step.
About Jammertest 2025
Jammertest 2025, now in its fourth year, is a unique collaborative initiative hosted by Norwegian authorities such as the Norwegian Public Roads Administration, Communications Authority, Defense Research Establishment, and others.

The event exposes participating technology—including ours—to controlled, real-world signal interference and cybersecurity threats, evaluating how systems behave under conditions like GNSS jamming and spoofing.
It provides an unparalleled environment for field data collection and system validation, all with the aim of reinforcing the security and reliability of essential infrastructure.
Thank you and next steps
We deeply appreciate the support and collaboration from Jammertest, Testnor, Calian, Septentrio, Ublox, and Adrelys. These partnerships enable us to continuously improve our technology.
