Well well well, anybody think they won’t deploy this throughout the country?
Well it does revolve heavily around military satellites and was put in place for the military. We get to use it as a convenience.

If it looks like we are under attack, you bet. Who wants a foreign version of JDAM targeting our assets? Who wants alien sapper teams navigating by GPS?
GPS jammers are widely available. You can buy them on the 'Net, or build your own. They are illegal, but that hasn't stopped people from using them.
There was a case a few years ago in NJ: GPS reception around the Newark airport area was having an outage every day, about the same time. They set up direction-finding equipment, and identified a truck that was carrying a jamming transmitter.
It turned out the driver was using it to jam the GPS tracking device in his truck, so his employer wouldn't know what he was doing.
No one is explaining exactly what is going on, but I suspect the DoD is not testing jammers -- they are testing GPS receivers that are intended to be resistant to jamming.
