Latest Version of GPS Launches: The 
Air Force launched the first modernized Global Positioning System satellite built by Lockheed Martin aboard a Delta II rocket from Cape Canaveral AFS, Fla., at 11:37 pm Sunday night. The satellite, a GPS IIR-M, is the first in a series of eight GPS IIR satellites Lockheed is modernizing. Among the features provided by the new sats, once they reach initial operational capability, are two new military signals and a second civil signal on a different frequency, as well as a new antenna panel for increased signal power to receivers on the ground.
The Air Force has embraced new technical approaches like open mission systems and rapid software updates for cutting-edge aircraft like the B-21 and Collaborative Combat Aircraft. Increasingly, though, the service is also working to apply these to its older, “legacy” aircraft, officials said this week.
