New Reports Confirm Near-Perfect Performance Record for Civil GPS Service

Los Angeles Air Force Base, Calif. – June 16, 2017 – The U.S. Air Force released two technical reports demonstrating that the Global Positioning System (GPS) continues to deliver exceptional performance to civilian users around the world. GPS is a U.S. Air Force satellite system that provides highly dependable positioning, navigation, and timing (PNT) services to military and civilian users around the world, free of direct user charges. Operated by the 50th Space Wing at Schriever Air Force Base, Colorado, the GPS constellation provides precise PNT services worldwide 24-hours a day, seven days a week.

The 2014 and 2015 performance reports confirm that the GPS Standard Positioning Service (SPS) satisfied nearly all measurable performance commitments documented in the GPS SPS Performance Standard, furthering the status of GPS as the “Gold Standard” for PNT.  The GPS Directorate at the U.S. Air Force’s Space and Missile Systems Center commissioned the GPS SPS performance reports to enhance public transparency of the real-world performance of civil GPS.
