Norway and Finland have both reported problems with GPS signals in their northern regions this month. Both countries have been taking part in NATO’s exercise Trident Juncture, which has irked Russia. Reports of GPS interference related to Russian military activities have been reported in the past.

Norway’s aviation authority, Avinor, issued a notice to airmen of irregular navigation signals in airspace over eastern Finnmark between October 30 and November 7, according to The Observer in the UK and Yahoo news.

Aviation authorities in Finland issued similar notices in early November, warning air traffic of disruptions to GPS signals over the northern region of Lapland, which borders Finnmark.

Disruptions to Global Positioning System signals have been reported in northern Norway and Finland this month, overlapping with the final days of NATO’s exercise Trident Juncture, a massive military exercise that has drawn Russia’s ire.

A press officer for Widerøe, a Norway-based airline operating in the Nordics, told The Barents Observer at the beginning of November that pilots reported the loss of GPS while flying into airports in the northern Norwegian region of Finnmark, near the Russian border, though the officer stressed that pilots had alternative systems and there were no safety risks.

The director of Norway’s civil aviation authority told The Observer that organization was aware of disturbances to GPS signals in that region of the country but there is always notice given about planned jamming.

“It is difficult to say what the reasons could be, but there are reasons to believe it could be related to military exercise activities outside Norway’s [borders],” the director said.

ANS Finland’s operational director told Finnish news outlet Yle that the information had come from the Finnish Defense Forces but did not identify the source of the interference. “For safety reasons, we issued it for an expansive enough area so that pilots could be prepared not to rely solely on a GPS,” the operational director said. uk.news.yahoo.com
