- W1647441700 abstract "The requirements projected to the year 2000 for space-based communications facilities, including both personal communications and innovative services, are developed based upon anticipated demographic and economic growth for the seven major regions of the world. Projected growth requirements, when considered in light of operational factors such as orbit/spectrum crowding and the high investment costs of ground-based systems, suggest the need for new system concepts for communications. The concept of complexity inversion (placing high-cost systems in space and providing low-cost ground terminals to users) is examined and compared with the more conventional approach utiliizing land lines and extensive ground installations. The recommendation is made to develop the technology and capability to construct platforms in space, and the applicability of the Shuttle/Spacelab system in constructing large antenna systems in space is briefly considered." @default.
