On April 25, the Air Force's Global Positioning System (GPS) registered its most accurate signal yet. Using the numbers from a network of Jet Propulsion Laboratory-operated GPS tracking stations, Aerospace analysts calculated the signal-in-space accuracy of GPS to 38 centimeters (14.9 inches). The new record may be attributed to multiple improvements across the GPS enterprise. GPS's accuracy is beneficial to its 3 billion users. GPS is used from the swipe of a credit card to flying an aircraft around the globe. Learn more about the Global Positioning System at GPS.gov.
