Turn off Location, in your phone. If the phone complains, it's because it's spying on you. (Yes, the cell company can still triangulate your position, but it's no longer broadcasting your location via GPS)
P.S. I might be a little tin-foil-hatty...
GPS does not broadcast anything. It is receive only.
I only have location services turned on for those apps that require it (mapping apps). And I close the apps (swipe it up) when I am not using them.
