Air Force to Respond to GAO Report on GPS

Global Positioning System experts from Air Force Space Command and the Space and Missile Systems Center will hold a media roundtable teleconference tomorrow, September 24, at 2:30 p.m. Mountain Time (4:30 p.m. Eastern Time) to discuss the recent GAO report titled “Global Positioning System: Challenges in Sustaining and Upgrading Capabilities Persist.” Colonel David Buckman, AFSPC command lead for positioning, navigation and timing, and Colonel Bernard Gruber, commander of the Global Positioning System Wing at Los Angeles Air Force Base, will participate in the teleconference.

Air Force Space Command, which has responsibility for sustaining and maintaining the Global Positioning System, feels that the GAO report is overly pessimistic and doesn’t adequately acknowledge what AFSPC has done to address constellation sustainment, according to a press release issued from the Air Force, Peterson Air Force Base, Colorado. “The Air Force has created the largest, most accurate constellation, with the greatest capability, in the history of GPS, with 31 operational satellites currently on orbit,” stated the press release. “This is well above the 24 minimum satellites needed for a full constellation and to meet constellation performance standards. Since 1995, GPS has never failed to exceed performance standards.”

The release continued, “AFSPC is working to mitigate the challenges identified by the GAO through a number of activities, including: applying a ‘back-to-basics’ approach to acquisition, continuing to identify additional ways to maximize the life of our operational satellites, implementing robust mission assurance processes, and transforming our launch enterprise.”

The first GPS IIF satellite completed on-orbit testing and checkout and was set operational on August 26 as planned, the Air Force said, The GPS IIF program is ready for full rate production and continues to build confidence in its production line.  Through the institution of robust mission assurance processes, AFSPC is confident in the future of the GPS IIF program.

The follow-on program, GPS IIIA, recently completed critical design review, two months ahead of schedule, the Air Force said. “AFSPC is optimistic that its ‘back-to-basics’ approach, including stable requirements, mature technologies, and more government oversight, will ensure a successful program, providing the GPS IIIA and its ground segment, OCX, within a timeframe that maintains a robust GPS constellation and supports GPS users.”
