Space Station Caution and Warning Systems Design Considerations

Design considerations are discussed for Caution and Warning Systems for complicated space stations, with emphasis on practical reliability aspects and special consideration for on-orbit test and checkout requirements. Specific guidelines are given for design of the system, with discussion of each major facet to guide the design in early phases. An on-board checkout concept is introduced to keep the “System Has Failed” risk below a defined requirement. A simplified block diagram is shown to demonstrate interface isolation.
