Comment on Commercial Flights Are Experiencing 'Unthinkable' GPS Attacks and Nobody Knows What to Do
Dettweiler42@lemmyonline.com 10 months agoADIRUs will throw out bad GPS data if it disagrees with multiple IRUs, hence why there’s usually 3 on the aircraft.
If they’re using the older IRUs, the drift is corrected via redundancy and not GPS. Usually pilots will report drift based on their final IRU coordinates compared against GPS. Even then, they should still be checking their course with VOR.

Anyone with the ability to jam GPS can easily spoof VOR signals.

But in this case, they’re not. Plus, the crew are going to be the ones determining if their VOR/DME makes sense or not.

We don’t know that they aren’t spoofing VOR/DME as well. We might be seeing reports from affected aircraft, rather than specific targets.
