We wanted to get this intelligence to airlines and other aviators for security reasons," Isomaa added. He said that the warning had been issued for a large area as a safety precaution. "For safety reasons, we issued it for an expansive enough area so that pilots could be prepared not to rely solely on a GPS," he noted. However, he declined to state the source of the disruptions. Responding to an email query from Yle, Defence Force communications director Colonel Sami Nurmi also refused to comment on the matter, instead referring Yle to Ficora, the Finnish Communications Regulatory Authority. Previous warnings in Norway Last Friday, the online publication Barents Observer reported on GPS jamming affecting air traffic in northern Norway's Finnmark region.
A warning about possible GPS blocking in the region had been issued at the end of October when NATO kicked off major military exercises dubbed Trident Juncture in Norway. Finland also participated in the war games, which ended on Wednesday, 7 November. Meanwhile, Norway's aviation warning is still in force and is expected to end on Friday afternoon. Finland's ANS has also published the Norwegian advisory in a bulletin. The Norwegian advisory covers the Kirkkoniemi airport area near the Finnish and Russian borders and Norwegian authorities have speculated that the disruptions could become from Russia. Additional signal jamming was detected at least one year ago, which Norwegian officials also believed came from Russia.
The goal of the alleged Russian interference was "to demonstrate the capabilities for such actions," he said. Looking across the border The disturbance targeted the Finnish region of Lapland and parts of Norway near the border with Russia. The regional Widerøe airline confirmed its pilots had experienced GPS disruptions. But it said that pilots aboard civilian planes have several contingency systems to fall back when a GPS signal is lost. Sipila's comment came four days after NATO forces ended their two-week Trident Juncture exercise. The Oslo authorities have already accused Russia of disrupting the navigation system during Russia's Zapad-2017 drills.
