Posted: Monday, November 8, 2004

Aerojet engines contributed to the successful launch of a Boeing Delta II vehicle Saturday from Cape Canaveral Air Force Station, Fla. The payload on the Delta II was a Lockheed Martin NAVSTAR Global Positioning System military navigation satellite, GPS IIR-13.

Not only did Aerojet provide the second stage liquid engine and third stage control thruster on the launch vehicle; the company's 16 monopropellant thrusters also provided thrust for attitude and orbit control on the GPS satellite. Aerojet has produced the thrusters for every GPS block to date, and is currently making propulsion systems for Boeing's GPS IIF, a next generation system. The first GPS satellite was launched in 1978, with thruster development beginning at Aerojet's Redmond Operation in 1975.
