GPS Network Could Fail Next Year Leaving Sat Nav Useless, US Government Accountability Office Warns

The Global Positioning System (GPS) could collapse as early as 2010 due to a lack of investment in new satellites, the US government accountability office has told Congress.

It blamed the US Air Force, which runs the worldwide system free of charge and is responsible for modernising it, saying it had failed to take the necessary steps to keep the network of satellites running properly.
