The PEACESAT Project (Pan Pacific Education and Communication Experiments by Satellite) has been in daily operation for four years since April 1971. Initiated as an individual research project of a university faculty member, it has expanded to involve educational institutions in 12 countries or jurisdictions in the Pacific Basin. These institutions own and operate low-cost satellite ground terminals using the experimental satellite ATS-1 of the U.S. National Aeronautics and Space Administration. The satellite communication system is designed to support specialists and community leaders who have responsibilities for resolving social problems by linking them with sources of useful information. This report, consisting of contributions from project personnel, and including recorded conversations, transcriptions of PEACESAT exchanges, and occasional reports from the personnel, attempts to provide an insight into the potential social benefits provided from a system of the type used in the PEACESAT experiment. The technical system of the experiment is also briefly explained. (LL)
