    • Abstract:
      The Department of Defense announced today that it intends to stop procuring Global Positioning System

      (GPS) satellites with the capability to intentionally degrade the accuracy of civil signals.

      This capability, known as Selective Availability (SA), will no longer be present in the next generation of GPS


      Although the United States stopped the intentional degradation of GPS satellite signals by setting SA levels

      to zero in May 2000, this action to permanently remove SA eliminates a source of uncertainty in GPS

      performance that has been of concern to civil GPS users worldwide for some time. While this action will not

      materially improve the performance of the system, it does reflect the United States’ strong commitment to users

      by reinforcing that this global utility can be counted on to support peaceful civil applications around the globe.

      The decision to remove the capability from the next generation GPS satellites was approved by the

      President after a recommendation from DoD. The move coincides with the U.S. Air Force’s solicitation to

      purchase the next generation of GPS satellites known as GPS III.

      GPS is a dual-use, satellite-based system that provides accurate positioning, navigation and timing

      information to users worldwide. Originally developed by the Department of Defense as a military system, GPS

      has become a global utility. It benefits users around the world in many different applications, including aviation,

      road, marine and rail navigation, telecommunications, emergency response, resource exploration, mining and

      construction, financial transactions and many more.
