Air Force Vows Smoother GPS Flight System Update

摘要

The U.S. Air Force said Nov. 30 it expects no interruption in GPS services as it begins a transition to a new block of ground-control software for the fleet of timing and navigation satellites.rnThe Air Force's fleet of 30 operational GPS satellites is currently flown using the GPS Operational Control Segment, which was designed and built by Boeing Defense, Space & Security of St. Louis. By 2015, control of the GPS fleet will transition to a next-generation ground segment, dubbed GPS OCX, that is being designed by Raytheon Intelligence and Information Systems of Aurora, Colo., under an $886 million contract awarded in 2009.
