There is a need for knowledge based fault detection and diagnostics on the future generation of space vehicles. These vehicles have a more demanding set of requirements than today's vehicles. A tank pressurization system was chosen to explore the potential for an on-board knowledge based fault detection and diagnostic system. Specific tasks were to investigate sensor based diagnostics, appropriate levels of knowledge representation, the generation of further diagnostic tests, the diagnosis of two failures, and effective forms of graphical representation.
