How to Block GPS?

Answer

To block the (gps) Global Positioning System signals, drive a permanently mounted, GPS-equipped vehicle into an underground parking structure to quickly and simply block the GPS signal then place a hand-held receiver in an environment that will block GPS signals also placing it in a water-tight bag underwater will block the signal, as will carrying into a basement then test other marginal ways to block the signal and because GPS receivers will not get a signal inside a building, under dense foliage such as in a forest, the GPS receivers need to be able to see a minimum of three satellites for a latitude and longitude fix, they need four satellites for latitude, longitude and altitude calculations.

The only reliable and legal way to block GPS is by not using anything with GPS enabled. There are GPS signal jammers, but they're illegal to own and use in many places.
