"Capabilities and Limitations of Space Communication Systems."

The paper "Capabilities and Limitations of Space Communication Systems" is part of a General Electric Technical Information Series prepared for the Apollo Support Department. The abstract states "A survey and study of the basic parameters of information transfer systems for space communications is presented in this paper, to familiarize systems checkout and on communication engineers with the state-of-the-art and trends in this field. Both current and anticipated requirements for space communication systems are briefly considered. Some of the problems that exist in space communication are presented, along with a general review of current communication systems, their capabilities, and limitations as well as possible improvements in the areas of spacecraft directional antennas, ground stations and antennas, spacecraft transmitter power, and telemetry systems. It is concluded that the increased capabilities expected by the end of this decade should make adequate and reliable space communication possible for most predicted communication needs of future space missions at lunar and near-planet ranges."
