International Telemetering Conference Proceedings / September 15-17, 1969 / Sheraton Park Hotel, Washington, D.C. === The original Apollo Space Suit Communications System (SCC) was designed to accommodate one Extravehicular Astronaut. Early in 1967, NAS.N established a requirement for an extravehicular Communications System (EVCS) which would enable two astronauts to simultaneously explore the lunar surface. Included in this requirement was a telemetry subsystem to monitor the performance of the portable life support system (PLSS), space suit performance and body functions of each astronaut while on the lunar surface. This paper reviews the EVCS telemetry subsystem design including electrical and functional capability, packaging techniques, reliability and configuration control programs utilized in meeting the stringent requirements of a miniature, high reliability, man-rated electronic system for space applications.
