The United States has made few preparations for such attacks on its homeland and infrastructure, despite mishaps at home that have disrupted air traffic control systems and regular press reports of American weapons systems degraded by jamming and spoofing overseas.

looks like our systems need some sort of security update. problem is, would all of our GPS receivers need updated too? maybe a GPS 2.0 or something?

Or we just arm our gps satellites and let them pick out and disable offensive satellites. Might be cheaper.
The only thing that can stop a bad GPS satellite is a good GPS satellite with a gun.
