ABSTRACT
The use of satellite technology by broadcasters is highly developed and in widespread use throughout the world. Satellites are routinely used for broadcast television and radio backhaul and network distribution services, and they provide low cost, reliable operation. These and many other services are made possible due to the unique characteristics of satellites placed in the geosynchronous satellite orbit. The capability of a single quasi-stationary repeater in the sky, visible to large, contiguous regions, offers a wide variety of distribution capabilities for terrestrial broadcast service providers as well as the public in general. Satellite communications are also particularly useful for mobile services, long-distance communication services, and for services across difficult terrain. Analog and digital satellite transmission systems are considered in detail in this chapter.
