> A new report from Norway's defence research institute FFI warns that the loss of satellite-based navigation and timing signals (GNSS) could seriously weaken Norway's total defence. FFI proposes six measures, including ground-based backup systems and national robustness standards, which will now form the basis for an updated national strategy.

**Norway's Defence Research Establishment, FFI, [has published](https://www.ffi.no/aktuelt/nyheter/nar-satellittnavigasjonen-svikter-blir-totalforsvaret-sarbart) a report on the risks of losing satellite-based positioning, navigation and timing signals, known as PNT. It concludes such failures could seriously weaken Norway's total defence. The Ministry of Trade, Industry and Fisheries commissioned the report.**

FFI mapped GNSS dependency across nine critical functions, including power supply, telecommunications, transport, payment systems, food distribution and emergency services. Most sectors carry medium vulnerability, FFI found. Emergency services face medium-to-high risk, since they rely on GNSS for localisation, navigation and resource management.

FFI describes GNSS signals as "weak and highly vulnerable to electromagnetic interference," both natural and man-made. It singles out spoofing, feeding false position or timing data into a receiver, as more dangerous than jamming, because it is harder to detect and can disrupt operations immediately.

FFI recommends six measures. These include testing navigation equipment for weaknesses, setting national PNT robustness standards, building ground-based backup timing references, and fitting multi-GNSS receivers and anti-jamming antennas.

Minister of Fisheries and Ocean Policy Marianne Sivertsen Næss [said](https://www.regjeringen.no/no/aktuelt/ny-side7/id3172189/) GNSS disruptions have already become "a daily problem" in East Finnmark, "impacting transport, healthcare and police". She stated that the FFI report "gives us a systematic analysis of how vulnerable our society is to the loss of satellite-based PNT," and would feed into work on strengthening preparedness and total defence.

## FAQ

**What does the FFI report say about satellite-navigation failures and Norway's total defence?**

FFI concludes that losing satellite-based positioning, navigation and timing (PNT) signals could seriously weaken Norway's total defence. The report, commissioned by the Ministry of Trade, Industry and Fisheries, mapped GNSS dependency across nine critical societal functions to assess national vulnerability. Last fact-checked: 2026-09-21.

**Which sectors did FFI find most vulnerable to GNSS signal loss?**

FFI found most of the nine mapped sectors, including power supply, telecommunications, transport, payment systems and food distribution, carry medium vulnerability. Emergency services face medium-to-high risk because they depend on GNSS for localisation, navigation and resource management, making them especially exposed to signal disruption. Last fact-checked: 2026-09-21.

**What measures does FFI recommend to protect against GNSS spoofing and jamming?**

FFI recommends six measures, including testing navigation equipment for weaknesses, setting national PNT robustness standards, building ground-based backup timing references, and fitting multi-GNSS receivers with anti-jamming antennas. It warns spoofing is more dangerous than jamming since it is harder to detect. Last fact-checked: 2026-09-21.
