You are correct there are not two GPS systems, but the systems in vehicles might be less effected, because whatever is jamming the aircraft won't have line of sight on the ground.

That's according to a flight advisory just issued by the FAA, which warns pilots that their GPS signal "may be unreliable or unavailable" due to "GPS tests" that the Department of Defense will be conducting between January 20th and February 22nd. Details are fairly light beyond that, but the FAA does note that when the "tests" occur they will be active for 45 minutes, and be followed by 15 minutes of off time -- additional notices to p

It will only effect planes equipped with GPS for navigtion, nothing else.

As far as air-travel goes, I'm sure all will be fine because they can still use RADAR. They probably don't use GPS solely yet anyway, tho that is speculation on my part.
