The launch of an earlier GPS satellite aboard a Delta II.

A Delta II rocket launched at 06:10 GMT this morning, with the GPS IIR-19 navigation satellite. The spacecraft, which forms part of the US Air Force's NAVSTAR Global Positioning System, has been successfully delivered into a Medium Earth orbit.

The rocket flew in the 7925-9.5 configuration, with 9 GEM-40 solid-rocket boosters, an Extra Extended Long Tank Thor first stage, a Delta-K second stage, a Star 48B third stage, and a 9.5 ft (2.9m) diameter payload fairing. Launch was conducted by United Launch Alliance (ULA).

GPS IIR-19, also known as IIM-6 and SVN-48, will be placed in plane A, slot 4, replacing the GPS IIA-15 satellite. IIA-15 was launched in September 1992, and has been operating for over twice its design life. This was the 135th launch of the Delta II, and the twelfth orbital launch of 2008.
