A new Global Positioning System satellite was launched into space late Friday night atop an unmanned Atlas 5 rocket that lifted off from Cape Canaveral Air Force Station.
The rocket carried a GPS 2F-7 spacecraft which will join a constellation of other satellites already orbiting 11,000 miles (17,700 kilometres) above Earth. The GPS satellite will provide navigation for both military and civilian users.
The craft, when it becomes operational, will replace a 17-year-old satellite. The older satellite will be used as a back-up for the new one.
This was the second launch from Cape Canaveral in the US this week. A Delta 4 rocket lifted off on Monday, carrying a pair of military satellites.
