Abstract:
In 1982, NASA plans to launch the first TDRS into geosynchronous equatorial orbit using the Shuttle and the Inertial Upper Stage. Each TDRS will carry a highly flexible multifunction communication payload that services TDRS System users or Advanced Westar (AW) users while providing concurrent Westar C-band service. In the TDRS mode, two 4.9 meter diameter gimballed antennas provide single access S-band and/or K-band service, and a 30 element phased array provides 20 channel multiple access S-band service. Space Ground Link (SGL) communication with the White Sands Ground Station users a 2 meter gimballed K-band antenna. In the AW mode, K-band service is provided by a spacecraft switched TDMA transponder through four spot beams (two using the 4.9 meter antennas and two using separate feeds on the SGL antenna) and three area coverage beams (two from a body fixed dual feed antenna and one from an area feed assembly on the SGL antenna). C-band service is provided by a standard 12 channel Westar payload with its own 1.5 meter antenna. Nominal deployment is four satellites: two dedicated TDRS are at 41° and 171°W, and the AW and spare (or shared) satellites are at 91° and 83°W, respectively. TDRS is a 5000 pound satellite with momentum wheels for 3-axis control and a hydrazine reaction control system for momentum dumping and stationkeeping.
