The U.S. Air Force has selected Raytheon for a contract of $886 million to develop a new element of the Global Positioning System (GPS), called the Advanced Control Segment (OCX), to improve the accuracy of information from GPS satellites. The new segment will include anti-jam capabilities and improved security, accuracy, and reliability and will be based on a modern service-oriented architecture to integrate government and industry open-system standards. The GPS, a satellite-based radio navigation system for the military and the public, consists of three major segments: the user segment, the space segment, and the control segment, which includes a master control station and ground antennas.
