WASHINGTON โ€” The U.S. Air Force on May 27 successfully launched the first of a new generation of GPS satellites aboard a Delta 4 rocket from Cape Canaveral Air Force Station, Fla.

The GPS 2F-1 satellite was placed into a roughly 17,600-kilometer orbit and joins an operational constellation of 30 previous-generation GPS satellites, the Air Force press release said.

The GPS 2F satellites are more powerful than previous GPS satellites, generating more robust, jam-resistant signals, according to prime contractor Boeing Space and Intelligence Systems. The satellites will also provide a third civil signal known as L5 that will be used for commercial aviation and search and rescue operations. The satellites have 12-year design lives, longer than earlier GPS craft were intended to operate.

The GPS 2F satellites are the first to rely on the Air Forceโ€™s Evolved Expendable Launch Vehicle rockets. Previous GPS satellites were launched on the smaller Delta 2 rocket, which is being phased out by the service.
