The new GPS Military-Code Early Use hardware and software upgrade successfully took place on July 27 at the GPS Operational Control System at the Master Control Station at Schriever Air Force Base, Colorado and Alternate Master Control Stations at Vandenberg Air Force Base, California. All 22 GPS Block IIR-M, IIF and III space vehicles currently on orbit broadcast the encrypted M-Code signals, enhancing anti-jam and anti-spoof capabilities for the warfighter.
