There are GPS jammers, but their effectiveness is disputed.

by who?


Due to the tight control of GPS by the US gov, the Europeans
are develping their own system called GALILEO which will use
the same base frequency (L1) as the NAVSTAR which means most
consumer level GPS units will be compatible. Once this is
available, the idea of the US Gov 'turning off' GPS is moot.

Moot? Hardly. You think Galileo couldn't be jammed?
