WASHINGTON — The U.S. Air Force successfully launched the 11th satellite in its current-generation series of positioning, navigation and timing satellites Oct. 31 from Cape Canaveral Air Force Station in Florida aboard a United Launch Alliance Atlas 5 rocket.

The GPS 2F satellites, built by Boeing Network and Space Systems of El Segundo, California, provide better accuracy and resistance to jamming than the previous generation of GPS satellites, most of which are still in operation.

The Air Force confirmed the successful launch about three-and-a-half hours after the 12:13 p.m. liftoff. The last satellite in the GPS 2F series is expected to launch Feb. 3, 2016, Air Force officials said during a prelaunch conference call Oct. 22.
