Commercial Flights Are Experiencing ‘Unthinkable’ GPS Attacks and Nobody Knows What to Do::New “spoofing” attacks resulting in total navigation failure have been occurring above the Middle East for months, which is “highly significant” for airline safety.
What about GLONASS, Galilleo, or BDS? Are they all being equally jammed? Why wouldn’t they sync with all of them and use a consensus to determine accuracy? Like having multiple ntp servers.
The latest generations of gnss receivers have spoofing and jamming mitigation and detection features included with the chip, and multi-band rx technology to sync to more constellations simultaneously and do exactly what you’re talking about. Before then, the spoofing/jamming detection would likely need a software implementation after the receiver. There are different types of spoofing/jamming, all of which are detected and mitigated in different ways.
I don’t know the commercial aircraft industry standards for updating technology, but I wouldn’t be surprised if most commercial aircraft don’t have what you’re talking about.
