Not all of the US military’s Global Positioning System receivers have been functioning properly after the recent upgrade of the Global Positioning System command and control software, Gen. Robert Kehler, Air Force Space Command boss, told reporters Feb. 18 at AFA’s Air Warfare Symposium in Orlando, Fla. “It is not a problem with the command and control software, nor is it a problem with the navigation signal from the satellite. This is a receiver problem,” explained Kehler. He said the issue has been “isolated to a set of receivers,” meaning only “handfuls” are affected as opposed to large numbers. And, he said, “We have a fix; we know what the problem is.”
There is a new entrant in the highly competitive field of collaborative combat aircraft—semi-autonomous drones meant to fly alongside manned combat aircraft. Northrop Grumman unveiled its new Project Talon aircraft to a small group of reporters at the facilities of its subsidiary Scaled Composites.
