GPS jamming is a ‘side effect’ of Russian military activity, Finnish transport agency says – POLITICO

“It is possible that the interference currently observed in aviation is most likely a side effect of Russia’s self-protection” which is used “to prevent the navigation and control of drones controlled by GNSS (Global Navigation Satellite System) or by mobile frequencies”, Traficom said.

Regardless, the Finnish agency says it is safe to fly to and from Finland thanks to inertial-based navigation and ground-based navigation alternatives – although GPS remains ” the primary source of aviation navigation information.”

Finnair earlier this week suspended flights to Tartu, Estonia, for a month; the Estonian government announced its intention to discuss the issue with its EU and NATO partners.

“(The) North Atlantic Council yesterday (May 2) addressed recent malicious activities on allied territory and said that Russia’s hybrid operations, such as cyber and electronic interference, but also sabotage, acts of violence and disinformation campaigns have affected several NATO member states.” said a spokesperson for the Estonian Foreign Ministry, referring to a NATO statement released on Thursday.
