Lockheed gets greenlight for GPS III satellites

GPS, the heart of the Global Positioning System really is the network of satellites orbiting the globe and relaying signals to your Garmin. That network is now due for an upgrade, starting in the middle of the next decade.Earlier this week, Lockheed Martin announced that it had been awarded a $1.4 billion contract from the U.S. Air Force to build the next-generation system, known as GPS III. The goal is to deliver better accuracy and availability for both civilian and military users of the navigation technology (which, after all, was born as a military innovation).
