Abstract:

The results of an investigation of the feasibilitydesirability of conducting a demonstration experiment of ELFVLF radio transmissions from a satellite to ground are described. Major problem areas are identified, the limitations of available information are discussed, and approaches, involving both theoretical and experimental efforts, are suggested for obtaining the necessary quantitative engineering data to plan such an experiment. Some aspects of possible Air Force uses of an ELFVLF satellite communications system are also discussed.
