The satellite's integral propulsion system uses monomethyl hydrazine and nitrogen tetroxide bipropellant carried in four spherical titanium tanks. A single 490-newton(110-pound force) thruster is used for perigee augmentation and apogee burns, and thirteen 22-newton(5-pound force) thrusters are used for attitude control and stationkeeping maneuvers. Highly accurate antenna pointing control is provided by independent beacon tracking on each of the Ku-band reflector systems. The attitude control system uses an innovative combination of double-gimballed momentum wheels and magnetic field torquing, which minimizes the need for thruster use during normal on-station operations. 3, record 2, English, - double%2Dgimballed%20momentum%20wheel
