A multibeam, spherical-reflector satellite antenna for the 20-and 30-GHz bands. A multibeam antenna for satellite communication affords reuse of frequency allocations and flexibility in traffic routing. A multibeam satellite antenna is described that employs a spheroidal reflector in a compact periscope design. The aperture is 1. 5 meters in diameter radiating six beams in the 20-and 30-GHz satellite frequency bands. Electrical measurements indicate that this antenna is suitable for multibeam satellite use.  2, record 3, English, - spherical%20reflector%20satellite

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 22, English, - double%2Dgimballed%20momentum%20wheel
