CAPE CANAVERAL, Fla. -

The Air Force has launched a satellite from Cape Canaveral to be part of the existing navigation system for the military.

The latest Global Positioning System satellite rocketed into space Thursday morning from Cape Canaveral Air Force Station, which is separate from NASA's space center on the Florida coast.

The satellite was carried up by an unmanned Delta IV rocket.

The Air Force manages the navigation system to ensure there are at least 24 operational satellites at all times. This newly launched spacecraft includes an improved military signal that is more resistant to signal jamming in hostile environments.
