Operating Frequencies for Educational Satellite Services.
Singh, Jai P.
Part of a continuing study of application of communication satellites for helping to meet educational needs, this memorandum discusses operating frequencies for educational satellite services. Each of the factors affecting choice of transmission frequencies is identified and discussed in a separate section. Included among these factors are international radio regulations, with emphasis on frequency allocations, power-flux density restrictions, and the introduction of broadcasting-satellite systems; natural environmental effects, divided into those due to transionospheric propagation and those due to the earth's atmosphere; man-made environmental effects, in terms of various sharing limitations as well as the indigenous noise contribution to the overall system noise; hardware considerations, with an attempt to show the frequency dependence of system cost and performance; and interconnection and spectrum space considerations, covering the implications of educational telecommunication needs. The last section deals with various specific recommendations for educational interests in terms of frequency choice and related actions for domestic rule-making for incorporating the 1971 World Administrative Radio Conference (WARC) frequency allocations in the domestic frequency table.
