GPS Glitch Two Years Older than First Stated
On Wednesday, the GPS Directorate said further data analysis shows that a technical error affecting some Boeing GPS IIF satellites first appeared in 2011, two years earlier than originally stated, according to a Reuters report.
The error first appeared one year after the GPS IIF satellites became operational. The error affects the way the ground control system builds and uploads messages transmitted by the satellites, but does not affect the accuracy of GPS signals. It involves the ground-based software used to index messages.
Lockheed Martin runs the GPS ground control segment, which enables Air Force officials to operate all GPS satellites, including the IIF satellites built by Boeing.
