Fed: Planes flying in "commercial" airspace must get GPS

It will affect any aircraft dependent upon GPS, and without a VOR back-up,
that will be very dangerous. GPS is trivially easy to jam and almost as easy
to spoof. Airliners might get by en-route with INS, but small aircraft
dependent on GPS will be up the creek, and airliners on approach will be in
danger as well (especially if ILS is decommissioned, too). WAAS does not
help.
LAAS is harder to interfere with but interfering with the LAAS transmissions
isn't absolutely necessary to mess up the system. RAIM doesn't help against
spoofing, and although it may detect jamming, that doesn't help much, either,
if you're entirely dependent on GPS and you no longer have it.

And in fact ADS-B is trivially easy to spoof, too. So the airplanes "seen"
via ADS-B may not actually be there, or they may not be where they appear to
be.


Heady stuff! Looks like the FAA and the NextGen developers better start
spending more time with USA Today, so they can be up to speed on all this
stuff they never even tought of!
