Space Communications and the related problems and developments. Animation: Use of video for Space Communications requires highly directive antennas for power economy. Depicts enlargement of capture area of antennas located at terrestrial reception points. Efficiency in signal processing of the receiving equipment increased, to reduce intrinsic noise by reducing temperature of components. A satellite in Earth's orbit for space and terrestrial communications. Explains the Passive Sattelite Relay System using reflecting spheres; Single Orbiting Active Satellite System using line of sight communication, ideal for weather forecasting and mapping; and the sophisticated active Day Period Cry Satellite Orbiting System equipped with transponders.
