Development of direct broadcasting satellite systems in the USA

The technical and operational features of the proposed direct-to-the-home broadcasting satellite (DBS) systems are described and the domestic and international rules and regulations that guide their development are summarized. The characteristics of the eight high-powered DBS systems that have been granted construction permits for the 12.2-12.7 GHz band and the relevant domestic regulations are described. The corresponding international regulatory framework for the development of such systems is considered. The international and domestic rules for the development of medium-powered DBS systems in the 11.7-12.2 GHz band and the characteristics of the three systems proposed so far for this band are described. The generic capabilities and limitations of the two categories of DBS systems are compared and some of the factors that will affect their further development are discussed.
