This sounds rather dangerous. GPS was originally opened up to civilian use for the purpose of keeping flights on course, after the disaster of Korean Air Flight 007 straying into Soviet airspace and being shot down back in the 1980s.
I can't understand what is to be gained by deliberately trying to knock civilian airliners off course.
GPS guided drone attacks. Civilian GPS top out at 300 m a second. Anything beyond that is a missile and GPS refuses to work unless you have one of the special government GPS chips without the limiter.
Would that be relevant for a drone attack? I wouldn't think a drone that isn't operated by a state actor is likely to be moving that fast, and presumably a state actor could build their own chips without a limiter?
Thus the point of the spoofing. A drone will be moving much slower than 300 m/s, so spoofing GPS would be an attempt to force it off-course.
Ah, I see, I misunderstood what you meant
