A report by the U.S. Government Accountability Office (GAO) has revealed significant issues with the future of the GPS worldwide system. The report is entitled 'Significant Challenges in Sustaining and Upgrading Widely Used Capabilities' and was released last week.

The report states it’s uncertain whether the Air Force will be able to acquire new satellites in time to maintain current GPS service without interruption. If not, some military operations and some civilian users could be adversely affected.

“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,” according to the report. A summary report is available at Inside GNSS.
