Why space broadcasting?

This article examines some nontechnical factors that will influence both policy and technical decisions regarding operational space-television broadcasting. The reasons for using space broadcast for both community and general public services are examined. They include faster introduction of service in new areas, potentially lower cost, extension of program choice, and more efficient use of frequencies. These are considered with respect to the state of economic development and availability of existing service. Marked differences are found between developing and developed areas. It appears that developing areas could best initiate television service with a community satellite, whereas developed areas could best use the satellite for program equalization. For both areas, a combined system of both terrestrial stations and satellites appears to be the most cost-effective. Possibilities for spectrum conservation are considered along with areas needing further study.
