| Abstract: | Based on Bayesian network, a new method to diagnose satellite faults is presented. The Bayesian network model of physical processing of satellite is developed; the main ideas of Bayesian network model of satellite fault diagnosis are introduced; the method to make the symptom variables values into discrete forms is proposed; one example is given to illustrate the application of Bayesian network model for satellite fault diagnosis. |
