Geostationary platform - An application of the Space Station
Abstract
Aggregate communication payloads developed in the NASA LeRC study are presented, and platform bus concepts currently evolving in the NASA MSFC study are described. The payloads encompass varying mixes of FSS, DBS, and maritime mobile services, WARC region 2, intraregion 2, and CONUS Intelsat traffic into the Atlantic and Pacific Ocean regions. The major features of four representative payload scenarios as developed by Ford Aerospace are described: (1) Scenario II, an FSS satellite with DBS capability, contains conventional C- and Ku-band transponders with two times frequency reuse at C-band and three times frequency at Ku-band; (2) Scenario IV is a high capacity, high power video distribution satellite; (3) Scenario V has CONUS coverage, and can be described as a high capacity CONUS, FSS satellite payload that is designed to address the distributional characteristics of CONUS traffic; and (4) Scenario VI-A, is the first of a complementary pair of satellites designed to handle all of the WARC region 2 Intelsat traffic, intraregion 2 as well as AOR and POR traffic. It is noted that Scenarios II, IV and V can be accommodated by a platform requiring a single STS launch while that accomodating Scenario VI-A requires multiple launches.
