  • 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 ; satellites. ; 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.
