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 Space Development Agency added 21 satellites to its nascent data transport network in an Oct. 15 launch, the second mission in 10-month campaign to field 154 operational spacecraft.
