The Next Generation GPS

The satellite gurus over at Air Force Space Command are making progress on modernizing the equipment, ground control systems, and military-user tools needed to upgrade the Global Positioning System. According to a Wednesday release from AFSPC, eight of the latest Block IIR replenishment satellites will be modernized with new military codes and a civil signal, and the first GPS IIR-M is scheduled for launch later this year. The new signals will provide less vulnerability to interference and increased performance in accuracy, availability, integrity and reliability.
