GPS SATELLITES COULD START TO FAIL NEXT YEAR

Guardian, UK - US government officials are concerned that the quality of the Global Positioning System could begin to deteriorate as early as next year, resulting in regular blackouts and failures – or even dishing out inaccurate directions to millions of people worldwide.

The warning centers on the network of GPS satellites that constantly orbit the planet and beam signals back to the ground that help pinpoint your position on the Earth's surface.

The satellites are overseen by the US Air Force, which has maintained the GPS network since the early 1990s. According to a study by the US government accountability office, mismanagement and a lack of investment means that some of the crucial GPS satellites could begin to fail as early as next year.

"It is uncertain whether the Air Force will be able to acquire new satellites in time to maintain current GPS service without interruption," said the report, presented to Congress. "If not, some military operations and some civilian users could be adversely affected.". . .

The impact on ordinary users could be significant, with millions of satnav users potential victims of bad directions or failed services. There would also be similar side effects on the military, which uses GPS for mapping, reconnaissance and for tracking hostile targets.

Some suggest that it could also have an impact on the proliferation of so-called location applications on mobile handsets – just as applications on the iPhone and other GPS-enabled smartphones are starting to get more popular. . .
