The failure could affect those with GPS on their auto navigation systems, boats and cell phones.
"The Global Positioning System faces the possibility of failures and blackouts, a federal watchdog agency has warned the U.S. Congress. Mismanagement by and underinvestment by the U.S. Air Force places the GPS at risk of failure in 2010 and beyond. The problem: Delays in launching replacement satellites, among other things.
According to the Government Accountability Office report, "In recent years, the Air Force has struggled to successfully build GPS satellites within cost and schedule goals" as part of a $2 billion modernization program.
'If the Air Force does not meet its schedule goals for development of GPS IIIA satellites, there will be an increased likelihood that in 2010, as old satellites begin to fail, the overall GPS constellation will fall below the number of satellites required to provide the level of GPS service that the U.S. government commits to.'"
