International and domestic point-to-point communication satellite systems are expected to multiply throughout the decade. In developed regions, they will remain auxiliary to the overall ground communication complex, even though very significant in dollar volume. In many underdeveloped regions, however, point-to-point systems could become the primary means of communication. If potential users of high-power satellites make the necessary arrangements for frequency assignments, user agreements, financing, regulation, and legislation (both national and international) and establish appropriate interfaces with other communication entities and systems, then many new applications with large growth potential can be developed for populated as well as underdeveloped regions. Without support on the order of $200 million per year to the development of the space segment, however, no dramatic new services or improvements in communications via satellite will occur in this decade. 11 pp.
