Fourth Global Positioning System Satellite Launched for the Air Force in 2014.

United Launch Alliance Atlas V blasts off with the GPS IIF-8 mission for the U.S. Air ForceCape Canaveral Air Force Station, Fla., (Oct. 29, 2014) – A United Launch Alliance (ULA) Atlas V rocket successfully launched the eighth Global Positioning System (GPS) IIF-8 satellite for the U.S. Air Force at 1:21 p.m. EDT today from Space Launch Complex-41. This is ULA’s 12th launch in 2014, and the 89th successful launch since the company was formed in December 2006.

“ULA is honored to work with this world-class U.S. government and contractor mission team, and we are very proud to have delivered  the GPS IIF-8 satellite to orbit today on the 50th Atlas V mission,” said Jim Sponnick, ULA vice president, Atlas and Delta Programs. “Achieving 50 Atlas missions with 100 percent mission success is a tribute to this team’s sustained focus on one mission at a time and dedication to reliably meeting our customer’s launch needs.”

This mission was launched aboard an Atlas V Evolved Expendable Launch Vehicle (EELV) 401 configuration vehicle, which includes a 4-meter-diameter payload fairing. The Atlas booster for this mission was powered by the RD AMROSS RD-180 engine, and the Centaur upper stage was powered by a single Aerojet Rocketdyne RL10A engine.

ULA’s next launch is the Delta IV Heavy Exploration Flight Test (EFT-1) mission of NASA’s Orion spacecraft for Lockheed Martin scheduled for Dec. 4 from Space Launch Complex-37 at Cape Canaveral Air Force Station, Florida.

GPS IIF-8 is the eighth in a series of next generation GPS satellites and will join a worldwide timing and navigation system utilizing 24 satellites in six different planes, with a minimum of four satellites per plane positioned in orbit approximately 11,000 miles above the Earth’s surface. The GPS IIF series provides improved accuracy and enhanced performance for GPS users.
