Finland’s national airline Finnair has announced the suspension of flights to the Estonian city of Tartu for a period of one month.
The move comes after two Helsinki-Tartu flights had to turn back to Helsinki Airport last week when GPS disruptions prevented the aircraft from landing in Tartu.

The flights are being suspended for one month in order to give the airport time to build an approach system that does not rely on a GPS signal.
The Finnish Transport and Communications Agency Traficom reported a five-fold increase in GPS jamming incidents last year, which one security specialist said was likely part of Russia’s hybrid strategy.
If GPS jamming is detected or suspected, pilots are advised to use radar or other systems independent of GPS signals.
