Stationed at 101.2 deg W. DirecTV, Inc. is a subsidiary of Hughes Communications and offers commercial satellite television service to the US. The orbital part of the system consists of 3 Hughes-built geosynchronous satellites. Broadcast services began in mid-1994. Competitors include the similar Primestar and USSB services, as well as older C-band satellite services and cable TV companies. Spacecraft: DirecTV uses the Hughes HS-601 spacecraft design.3-Axis stabilised, zero momentum biased control system. Two solar arrays (4 panels each side) span 31 meters and generate 4.3 kW power. Payload: The 2.5 m diameter graphite transmit reflector performs beam shaping.16 x 120 watt Ka-Band (12.2 - 12.7 GHz) transponders with 48-53 dBw EIRP and 24 MHz bandwidth. Power is higher in areas with heavy rain. The high power combined with Reed Solomon error correction coding allow the use of small 18 inch antennas by customers.
