There are GPS jammers, but their effectiveness is disputed.

by who?

Supposedly the Russians and supposedly some used against
US operations in Afghanistan.



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?

Sure it could. But it would take a lot of effort to jam
anything more than a localized region. It's not like someone
sitting in some secret bunker somewhere can fire up their
Acme GPS Super Jammer and knock out the whole affair.
