- W3021085513 abstract "The communications mission of RCA Satcom entails antenna beam coverage of all fifty states, with Hawaiian service provided by an offset spot from the primary beam for the contiguous 48 states and Alaska. To achieve minimum cost per channel in the competitive U.S. domestic market, Globcom and Alascom specified that their satellite should (1) incorporate 24 wide-band transponder channels in the commercial, 4/6 GHz band, (2) contain sufficient power and orbit control capacity to maintain all 24 channels operating continuously for a minimum of eight years, and (3) be compatible with the Delta 3914 launch vehicle, whose development they had funded jointly with the McDonnell-Douglas Astronautics Corporation at no cost to the U.S. government. This combination of requirements thus defined a communications satellite whose channel capacity is twice that of other current Delta class spacecraft but whose cost, including the launch vehicle, is significantly less than that of the corresponding 24-channel Atlas-Centaur class spacecraft designs. To meet these demands weight-optimized designs were needed in four key subsystem areas: antennas, transponder multiplexers, power supply, and attitude control as well as in the structure itself. The resultant three-axis stabilized spacecraft design with sun-oriented solar panels provides maximum power and weight capability to the primary communications payload within the launch vehicle envelope." @default.
