Dod Permanently Discontinues Procurement Of Global Positioning System
Selective Availability
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.
