2 SOPS keeps GPS flying!

Tech Sgt Steve German from the Defense Media Agency shows how the 2nd Space Operations Squadron at Schriever Air Force Base, Colorado keeps GPS flying! The squadron currently flys the GPS constellation of more than 30 operational satellites, the most satellites and the greatest capability in history. GPS is widely used by both military and civilian users throughout the World. The Air Force launched the seventh of its current block of IIR-M satellites in April, and will launch another one this Fall followed by the first of 12 Block IIF satellites in early Fiscal 2010. The IIF's sophisticated L-band payload will include new hardware that serves the civil user community. The next generation of GPS satellites, the GPS IIIA, with additional navigation signals for both civilian and military users will improve the accuracy and availability for all users. GPS IIIA is scheduled for first launch in 2014.
