Russian GPS spoofing detected at low altitudes in Sør-Varanger, Norway.

During the week of 9–13 June 2025, Norway’s National Communications Authority detected GPS spoofing affecting airspace over eastern Sør-Varanger, close to Norway’s border with Russia. Nkom specialists conducted helicopter-based measurements that confirmed manipulated Global Navigation Satellite System (GNSS) signals at altitudes as low as 150 metres above ground level. The findings represented a significant downward extension of previously observed interference, which had generally affected aircraft flying at higher altitudes over eastern Finnmark. The interference was intermittent and concentrated in the eastern parts of Sør-Varanger municipality rather than uniformly affecting the entire region. Preliminary analysis of the recorded radio signals indicated that they originated from Russian territory, although the transmitting equipment and exact location were not publicly identified. The spoofing occurred against a background of persistent GPS jamming that had affected aviation operations in eastern Finnmark for several years.
