On Thursday and Friday, two Finnair flights from Helsinki to the Estonian city of Tartu were forced by the GPS jamming to turn around and return to Finland as they were unable to navigate safely to their planned destination. https://www.ft.com/content/37776b16-0b92-4a23-9f90-199d45d955c3

@LukaszOleall airliners have inertial navigation because of GPS jamming. Before GPS this was the main way in planes and only way in submarines

@JohnLoader6 I have some small experience with both inertial navigation systems and VOR navigation in aircraft but am not a pilot nor do I know airliners. In the absence of GPS I think I would rather rely primarily on VORs because inertial systems accumulate error. Having said that, maybe you can't use VORs in the affected areas (they need ground-based beacons). Anyway, having both available would be fantastic.

@JohnLoader6
Sure.

And maybe, the pilots would rather not do that near a busy commercial airport.

It's one thing if you have to do it because you have no other option. An entirely different if you have a completely safe option to divert to a different airport.

@LukaszOlejnik @metacurity that’s not… shocking independently, but … not good.

@hacks4pancakes @LukaszOlejnik @metacurity Then again, and airport that refuses to invest in proper navigation equipment should be VFR only anyway... GPS jammers aren't expensive, even Newark airport has been shut down by a handheld one...

@LukaszOlejnik Tartu is a tiny airport that only Finnair services, after a long gap, and only because they get PAID to do so by the city council. It has something like 1000 passengers per year...

@LukaszOlejnik I guess the fact that most systems only use #NAVSTAR-#GPS and not #COMPASS & #GLONASS as well complicate things.

Sadly to appeasr #US #hegemony interests, the #EU downgraded #Galileo into a #SBAS instead of a real, independent #GNSS, making it easier to jam than GPS!
