Pratt & Whitney Rocketdyne once again has demonstrated its large payload lift capabilities by successfully boosting the second GPS- IIF2 navigation satellite for the U.S. government launched from Cape Canaveral Air Force Station, Fla. The satellite was onboard a United Launch Alliance Delta IV-Medium rocket, powered by a Pratt & Whitney Rocketdyne RS-68 booster engine and an RL10B-2 upper-stage engine. Pratt & Whitney Rocketdyne is a United Technologies Corp. (NYSE: UTX) company.
GPS-IIF2 is the second in a series of 12 new GPS satellites designed to improve navigational accuracy for civil, commercial and defense applications worldwide. It features more capability and improve mission performance, including predicted signal accuracy that is two times greater than heritage satellites; a 12-year lifespan that provides longer service and reduced operating costs; and a military signal for better resistance to jamming in hostile conflict areas. The RS-68 is a hydrogen-fueled engine designed for heavy-lift with 758,000 pounds of vacuum thrust and 663,000 pounds of sea-level thrust. The RL10B-2 is a cryogenic upper-stage engine that provides 465 seconds of specific impulse and 24,750 pounds of thrust.
