That's one way to do it.
Or avionics companies could sell modern equipment that uses multiple constellations (GPS, GLONASS, Galileo), is capable of acquiring more satellites at a time than a 20 year old system, and has basic jamming protection like ignoring spurious signals. You know: like consumer devices have been doing for years.
Then the commercial operators could install them in their aircraft.
First Glonass is a mess, missing quite a few operational satellites Galileo is just ramping up.
Interms of what is broadcast they still work on the same principle satellites broadcast time receiver does something like a linear least squares fit to estimate position, and time.
Mixing all the sources and doing a linear least squares like fit means the bad guy has to spoof more signals, and this system will be more robust but it is susceptible to the same attack just ramped up a bit
Just equip the airliners with modified AGM-88 HARM missiles to deal with the jammers.
Yea then they just start shooting down everything randomly,
And really want needs to be modified on the missiles? Sounds more like an airliner issue to me...
Sounds like they should remove the explosive part before putting into an airliner but maybe that's just me
