If the link does not work the article says the Loran network is being recommissioned in case of GPS satellite failure.

"In case of GPS failure". LOL That's classic. We already train for that. As a matter of fact you should only be using a GPS as a back-up. Individuals need not forget our basic map reading and land navigation. Murphy's law usually is in effect when it comes to GPS. When you need it, it has taken a crap so, you must be able to fall back on the dying art of map reading. I train civilians who are going into Iraq and Afghanistan and it always amazes me when they say "Why do we need a map reading class when we have GPS?" The funny thing is, I'll ask them if they know how to use their GPS and the usual answer is, "I'll figure it out when I get there". Uggghhhh

GPS may not be prone to failure, but it is extremely easy to jam. It is a simple, fixed frequency with such a weak signal that a barrage jammer can easily overpower it, or spoof it.
