“GPS attacks” shows picture of sonar
Meh, close enough.
Should have shown some invisible radio waves
If only there were still a backup like LORAN. It wasn’t as accurate as GPS, but it would still get you to your destination.
VOR and NDB stations keep getting decommissioned as well.Sounds like a James Bond movie
Have planes stopped using INS?
I believe they’re available as backup but re-calibrate themselves with GPS coordinates if available. This is not a problem when GPS jamming is used but becomes an issue with spoofing - the pilots need to monitor for it.
I think they talk about it in this video by flightradar24 somewhere: https://youtu.be/4dG_Whxzdkk
