Russia suspected of GPS jamming during Nato exercises
 

Last Tuesday Finnish air traffic control officials warned civil aviation about large-scale GPS signal disruptions in northern Finland.

It was the first such notice issued by Finland's state-run Air Navigation Services in an official Notice to Airmen (NOTAM), in which it advised that the disturbances began on Tuesday and continued until midnight on Wednesday.

According to ANS operations director Heikki Isomaa, the warning was prompted by information obtained from sources such as Finland's Defence Forces.

Last autumn Norway's equivalent of Ficora, Nkom, speculated that the GPS disruptions were coming from Russia.

Really? And what is purpose for for Russia to discover to NATO characteristics of their technology. IMHO, it is much more probable that NATO tests fighting in condition of GPS interference.

Poor Russians. Always blamed for anything bad happening in the galaxy.

GPS disruptions typical during military exercises
 

Happens several times a year with warning and likely on a smaller scale without warning.

Yup.
NOTAMs tend to extend to pages and pages - mostly comprising of CLSD and rarely AVBL.
Welcome to Russia, Comrade.

Happened along RUS-UKR border too. A pilot told me (I'm a handling agent), they flew from Larnaca to Moscow, and for about 20 mins they had no GPS. After they reported problem, other aircraft along their path did the same.

The jamming is occurring around eastern mediteran, probably due to Syria Conflict, it has happened to me several times over Cypriotic/Turkish airspace, if its the Russians, Turks, Israelis who knows. But it has nothing to do with Ukraine/russian border.

And people are talking about allow autonomous aerial taxis that will rely on GPS???

Well, easy to jam.

Spoofing (unless you're very close to the receiver) is a whole different ballgame.

They like to do that in/around the Kremlin here in Moscow when his nibs is in. To make sure you can't fly an off the shelf drone over the Kremlin they spoof the location of Vnukovo airport. Sometimes you get this interference miles away. Great fun trying to get anywhere while the GPS in your navigation device thinks you're 30 kilometers from where you actually are.

When we talk about satellite navigation, people usually associate it with "only" GPS. However, there are multiple GNSS systems deployed and modern smartphones, for example, can utilize different GNSS constellations. There are American GPS, Russian Glonass, Chinese BeiDou and the forthcoming European Galileo.

I'm curious, does anyone know how the avionics in typical modern airliner actually use the satellite navigation? Is it only GPS or a combination of all systems, or only some of those? I mean If only GPS is jammed, does the system notice this and switch over, or prefer one over another?

Not sure EXACTLY who I would point the finger at but there is extensive GPS jamming and possibly spoofing going on between Cyprus and the coast of Lebanon/Syria. I have suffered several GPS outages in the area. More worrying, on one occassion we had apparently correct but different positions from both the GPS units. Theis resulted in the Capt and FO FMS positions in disagreement by 15 miles.

I now disable GPS updates in that area.

LS8driver, most Western aircraft rely on the US GPS. Some of the more modern ones are also able to receive Galileo signals (A350, for example) but I don't know if they actually use these data.
