The Defense Department announced Tuesday that it would eliminate the selective availability feature on new Global Positioning System satellites. That decision coincides with the view expressed earlier this year by the National Space-based Positioning, Navigation, and Timing Advisory Board. The Pentagon stopped using the SA feature, which permitted satellite operators to intentionally degrade the GPS signal, in May 2000, but the advisory group believes that the continued inclusion of the SA feature generated international mistrust at a time when alternatives to GPS are emerging.
The Air Force is launching an effort to develop a new stand-off missile with a range of 1,000 nautical miles, or 1,150 miles, that would eventually be used for both air-to-air and air-to-surface missions.
