Space Shuttle avionics redundancy management
Abstract
An overview is presented of the current Space Shuttle avionics redundancy management system. The requirements placed upon the system, stemming from mission success, flight safety, and cost considerations, are reviewed. The avionic system configuration is described, showing the physical and functional interfaces among the various subsystem elements, and the redundancy levels for the elements are highlighted. Then the manner in which the redundancy is managed, utilizing various fault detection and identification, system reconfiguration and signal selection techniques, is outlined. Finally, an approach to system performance assessment is described, and several key design issues under consideration are discussed.
