Anyway, airports are highly dependent on the correct functioning of all the instruments involved in IFR approaches. Whether it's ILS, MLS, GPS, GBAS-LS or GNSS

Anyway, airports are highly dependent on the correct functioning of all the instruments involved in IFR approaches. Whether it's ILS, MLS, GPS, GBAS-LS or GNSS; spoofing, jamming and replay attacks may imply the capability to degrade or disrupt airport operations. Usenix is not publishing techniques for military grade electronic warfare... I'd hope so.
