Aerojet Rocketdyne, a GenCorp (NYSE: GY) company, said it has propelled the fifth Global Positioning System IIF military navigation satellite into orbit.
The GPS IIF-5 satellite was launched from Cape Canaveral Air Force Station in Florida by a United Launch Alliance Delta IV medium rocket. Aerojet Rocketdyne propulsion included an RS-68 booster engine, an RL10B-2 upper-stage engine and multiple spacecraft attitude control thrusters.
During launch, the rocket was boosted off the pad by the RS-68 engine, with 758,000 pounds of vacuum thrust and 663,000 pounds of sea-level thrust.
Twelve Aerojet Rocketdyne monopropellant (hydrazine) thrusters in four modules on the Delta IV upper stage provided roll, pitch and yaw control as well as settling burns for the upper stage main engine.
The GPS satellite, built by The Boeing Company (NYSE: BA) in El Segundo, Calif., includes a pair of Aerojet Rocketdyne propulsion systems which will be used periodically to restore the satellites to their designated orbits and to eventually decommission them.
