Uh, the Pentagon isn't going to turn off your GPS. Not only is there an entire commercial industry surrounding GPS, your 911 PSAP is using GPS to locate that accident you just called in from your cell phone. "Turning off" GPS would take a presidential order at this point and a politician willing to shoulder the burden of civilian deaths. Ain't gonna happen.
Then why do the Pentagon have the option to do so? Why did they demand the same access to Europe's new sat nav system (refused thankfully)?
And regardless of whether they switch it off or not, systems can be hacked and anyone hacking into that system can switch it off or corrupt it.
And don't think it's difficult to hack into the Pentagon systems, they've admitted that there systems have been hacked many times.
On top of that access to GPS, the whole system is vulnerable to interference and tampering.
Like i said, i'm sticking with what's worked all my life, a waterproof map and compass. Nothing can go wrong with that. Even if the compass fails i can follow a map on the topography alone. Map only topographic navigation is a good thing to practice when you're out in not to serious situations, it only increases to your nav ability when you do have a compass, and can save you if, and it's a big if, your compass gets damaged.
