GoKawiilNorway's Jammertest exercise spoofed helicopter and plane GPS for 40 minutes over Andøya
During Norway's annual Jammertest exercise in 2024, engineers fed false satellite-navigation signals to a rescue helicopter and a small plane flying over Andøya, causing tracking screens to show erratic loops and jagged paths that didn't match the aircraft's real routes. The test, which examines how equipment reacts to jammed or spoofed GNSS signals, is scheduled again for mid-September this year amid rising real-world interference linked to Russia's war in Ukraine.
GoKawiil's interpretation of the reporting above, not reported fact.
GPS and other satellite navigation systems don't just guide aircraft—they also supply precise timing that underpins power grids, telecom networks, and financial systems, so successful spoofing has consequences well beyond aviation. With confirmed jamming incidents affecting RAF flights, daily disruptions reported by Sweden's Transport Agency, and satellite-based interference reported across Europe, exercises like Jammertest are becoming a critical way to test resilience before a real attack causes serious harm.
- Jammertest deliberately spoofs and jams GPS signals to study how aircraft and other systems respond to fake navigation data.
- Interference incidents tied to Russia's war in Ukraine have increased sharply, affecting military flights and civilian infrastructure across Europe.
- GNSS disruption threatens not just navigation but also the precise timing that power grids, telecoms, and financial systems depend on.
Suunto MC-2 Mirror Compass — When GPS signals can be spoofed into showing a helicopter flying into the sea, an analog backup suddenly looks brilliant. The Suunto MC-2 is a full-featured baseplate compass with a sighting mirror and declination adjustment, and it cannot be jammed, spoofed, or knocked offline by satellite interference. It's the classic fallback every navigator should keep in a pocket.
