A Scientific Lunar Payload Communications System

Abstract

Based on the selection of scientific instruments suitable for application to the payload, conceptual designs were synthesized of payload packages, including the supporting subsystems. Parametric and/or conceptual design studies were conducted of such areas as communications. The primary communications link was to be payload to lunar survey probe communication facility carried with the Apollo vehicle, e.g., modified LEM. No burden was to be placed on the basic Apollo communication system. Payload-to-earth link was also to be considered as an alternate mode, particularly for the long duration instrument operation. The communications system described in this report is a natural outgrowth of the mission requirements and presents a realistic approach to a solution of the communications problems. As such, the system described could be readily instrumented, utilizing current state-of-the-art hardware and techniques.
