Intelligent diagnosis system is applied to fault in spacecraft. Dynamic Uncertain Causality Graph (DUCG) a new probability graphic model with many advantages. In this paper, DUGG spacecraft: introducing conditional functional events into ordinary DUCG deal spacecraft multi-conditions. Now, has been tested 16 typical faults 100% accuracy.
