The U.S. Air Force is set to launch the 11th Global Positioning System (GPS) IIF series satellite (GPS IIF-11) on Friday.

The Air Force and launch provider United Launch Alliance (ULA) plan to launch GPS IIF-11 from an Atlas V vehicle on Oct. 30 from Space Launch Complex 41 at Cape Canaveral Air Force Station, Fla..
