Space Station Freedom Distributed Systems-An Overview

The primary subsystems on Space Station Freedom are referred to as distributed systems. These systems include structures and mechanisms, electrical power, data management, internal audio/video, thermal control, man-systems, and the environmental control and life support systems. This paper describes the architectural layout of Work Package One {WP01) distributed systems within the Habitation and U.S. Laboratory modules and provides a brief description of each of these systems. Emphasis is placed on the environmental control and life support systems and the test plan to qualify these systems for flight.
