GPS Failure in 2012?
It wouldn’t be a total catastrophe, but it could certainly cause lots of trouble for transportation systems that rely on GPS, especially passenger airlines.
Existing satellites are ageing, and replacements are behind schedule and over budget, according to a report from the US Government Accountability Office.
Satnavs and other GPS devices calculate their position by comparing time signals from at least four satellites. To keep that many within range at all times requires a fleet of at least 24. For now there are 31 operating, but 13 of them are more than four years past their design lifetime.
The first replacement “block IIF” satellites are not due to launch till November, three years behind schedule, and the GAO predicts a 20 per cent chance that the fleet will drop below 24 at times in 2011 and 2012. That wouldn’t cause GPS to shut down, but its accuracy would drop unpredictably.
And you wouldn’t want to trust an unreliable GPS…

im not trying to be the hater here i really like your blog. But your last few links have been weak bro.
Hi, I like all your postings, keep up the great work.
As far as the GPS failing, I have been reading on the internet that they are already starting to fail off and on here and there. I think it is from that huge hole NASA reported in our magnetosphere a few months ago for some unknown reason. Anyway, I hope it fixes itself and it all gets back to normal soon.
Sweety. A war is going to happen in 2012. One that will affect every square inch of land on this planet. I dont claim to know everything that will happen, and the future is always changeing, but this is the strongest future right now. The worst of it all will be the US, UK, China, and Japan. And everything is already starting right now. I advise everyone to 1) Do not get any vaccines. They're full of toxins that will actualy weaken you even worse then the actualy sickness. 2) Train for endurance and speed. And 3) Practice stealth. If the streets are blocked and theres patrols all around you, silence is key. Avoid useing guns. They are FAR too loud to be of any use in the event of a sudden escape. Everyone be careful. And, like i said, this is NOT the only possible future. Things do change.
