Like Mike, I don't claim to know much about the GPS, and I didn't see the 60 Minutes report, but it was my understanding that at least a portion of the signal is encrypted. The signal available to us mortal (non-U.S. military) types has a built-in inaccuracy; while it is still accurate enough for some general use, it is not nearly as accurate as the signal available to the military. Anyone have more of the technical details, especially regarding the accuracy?
