As part of an analysis of educational needs and telecommunications requirements for future educational satellite systems, three studies were carried out. 1) The role of the computer in education was examined and both current status and future requirements were analyzed. Trade-offs between remote time sharing and remote batch process were explored as were trade-offs between on-campus minicomputers and shared centralized facilities. 2) An analysis was made of the various aspects of computer communications including the nature of communication terminals and the facilities for data-communications. 3) The use of communications satellites was examined for providing telecommunications for computer applications, with the emphasis on high-powered satellite systems involving small, interactive earth-terminals. The report concludes that what is needed to satisfy computing requirements is relatively high-power dedicated educational satellites capable of operation with a large number of small earth terminals. Although such a development would require a pooling of a large percentage of educational telecommunications users, the economies of such a system appear to be attractive compared to terrestrial-based communications for distances greater than 70 miles.
