The U.S. Government Accountability Office recently issued a report that claims that unless the Air Force puts up new GPS III satellites by 2010, older ones may stop working and service may fail. As of now there are 31 in orbit and although we only need 24 for positioning, the AF seems to have fallen behind in their maintenance. No need to fear yet, as the AF promises the new system will be up and running and may increase the signal by as much as 10 times the present rate.
