The effect of WARC-79 on efficient use of the geostationary satellite orbit
Abstract
There are problems of efficiency regarding the use of the geostationary satellite orbit by the Fixed-Satellite and the Broadcasting-Satellite services. The number of satellites that will be able to use the geostationary orbit could be greatly increased by changes in present practices. The use that can be made of the orbit for communication satellites is limited by interference between communications networks using the same frequency bands. The direct impact of WARC-79 decisions on orbit utilization efficiency is considered, taking into account technical standards, additional allocated bandwidth, broadcasting-satellite feeder link bands, and equitable access to the geostationary orbit. The indirect impact of WARC-79 on orbit utilization efficiency is examined along with WARC-1984/1985, giving attention to a stimulus for technical improvements, earth-station antenna sidelobes, satellite antenna radiation patterns, permissible internetwork interference level, and efficient transmission techniques.
