Many people around the world use Global Positioning System receivers and applications in their vehicles and cell phones to guide them to their destinations. But few people know much about the GPS signal itself.
Air Force Space Command Airmen of the 2nd Space Operations Squadron at Schriever Air Force Base, Colo., are the sole global providers of this free global utility through their command and control operations of the GPS constellation.
On any given day, more than 3.5 billion people around the world have access to GPS signals. With this access, civilians are finding more ways to apply GPS technology in their everyday lives. Today, GPS technology is used to increase productivity throughout global economies. In agriculture, the signal guides tractors and planting operations and has revolutionized global tracking of commercial goods. The signal allows faster emergency and disaster response efforts and has made personal fitness workouts more efficient.
