    So, first off. There is no reason for GPS jamming to cause a crash. Modern airliners have other ways to navigate.

    Now it is possible to target a single aircraft with GPS “spoofing” potentially, but both GPS and Galileo have ways round this (Navigation Message Authentication). I would like to think aircraft navigation systems should be using this system. But, even if not, I’d bet it’s still quite hard to reliably spoof a specific location to a moving aircraft.

      All (proper) Airlines have a simple solution for that, they just turn off GPS. Most of the time the ADIRS/ADIRU (bit too much to explain what it is here, the Wiki article is pretty good) does it automatically as well.

      For those interested, here’s a Video where GPS gets jammed and there’s an explanation on what they do and what happens, when it gets spoofed https://www.youtube.com/watch?v=4dG_Whxzdkk

        Yes, and also they have VOR/DME and ADF.

        With the inertial reference navigation, they’re not accurate enough for approaches like RNAV aren’t really viable.

        Some airports only have this as the instrument approach option with complex way points without radio navaids, and as such the flight may need to perform a visual approach or divert if jammed during the approach phase.

        In short, it’s not as bad as people might think, but can cause some problems.

      I had a look on the Galileo website and wiki page because you don’t hear about it much. Anyway it looks like the secure version isn’t open to businesses though maybe an exception for airlines would be prudent.

      Still though, planes flew long before GPS was a thing and were fine so should be fine today too. GPS was only released to the public after the USSR shot down a passenger plane that had gone off course.

        Historical context: the KAL007 incident immediately followed the intrusion and activity of a USAF Boeing RC-135 recon plane that was in literally the same spot earlier that day. This aircraft has the same radar signature as KAL007.

        The Soviets, in a hurry to shoot the spy plane signature hundreds of miles off civilian air routes while it was still in their territory (the second time the unresponsive KAL007 crossed it during the flight), shot it down.

        Yknow, as regularly and justifiably happens with spy balloons today.

        Russia does enough bad shit without the propaganda, going full onion just makes it seem laughable (not saying you are, this is just an extremely common take).

          Yes tensions were high at the time but it was a gigantic series of fuck ups that it vaguely sounds like you’re trying to excuse?

          The radar signature wasn’t an issue. They flew right up to it, knew it was a passenger plane (albeit possibly disguised), lied their asses off about various aspects of it, held back the flight recorder after they recovered it and initially denied having done it at all.

          Later we began to lie about small details: the plane was supposedly flying without running lights or strobe light, that tracer bullets were fired, or that I had radio contact with them on the emergency frequency of 121.5 megahertz.
