Schriever Air Force Base officials will host a ceremony at 3 p.m. Wednesday, July 15 in the wing headquarters building in honor of the Global Positioning System’s 20 years of full operational capability.

The Air Force confirmed the GPS full operational capability July 17, 1995, according to a Schriever AFB news release, which added that, during the last 20 years, GPS has become an integral part of technology that affects the lives of billions of people around the world.

Members of the 2nd and 19th Space Operations Squadrons in Colorado conduct the command and control mission of the 39-satellite GPS constellation. Beyond its essential capability for the military, GPS is a worldwide utility that provides the highest accuracy data available to people all around the world and enables such vital activities as weather forecasting, transportation, global commerce and farming/agriculture.

On Wednesday, the 45th Space Wing is scheduled to launch GPS IIF-10 aboard an Atlas V. Following a post launch presentation, Colorado Springs City Councilor Larry Bagley will present the GPS operators with a proclamation on behalf of the City Council declaring July 17 GPS Day.
