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 six-week government shutdown did not affect the hours flown by Air Force pilots, a service spokesperson told Air & Space Forces Magazine—avoiding what could have been a major blow at a time when flying hours are already lower than they have been in decades.
