GPS accuracy may plummet over the next decade like a satellite crashing to earth, if the parties in charge of maintaining it don't step up the job. That's according to recent studies, which state that the GPS system, which is based on the orbit of 24 to 32 satellites, will likely suffer if that minimum number can't be maintained.

There's a decent chance it might not be, either. Part of the issue lies in the fact that there isn't a single committee overseeing the system. Also at issue is that many of the satellites we rely on for GPS are upwards of 19 years old. The launching of new satellites has fallen behind schedule. The next one is set to launch this November, three years after initially planned.

As TidBITS points out, however, given how dependent the military is on GPS, it doesn't seem likely that it would let the accuracy drop so significantly.
