According to technical requirements of intelligence and automation for fault diagnosis of remote sensing satellite receiving system,fault characteristics of system is analyzed and the architecture of fault di-agnosis expert system is presented. Through analysis of the system equipment monitoring information and task flow,the establishment and analysis of the fault tree,using production rule for knowledge representa-tion,the knowledge base of fault diagnosis expert system is established and fault location is realized by heu-ristic model of forward reasoning. The fault diagnosis expert system is used in actual engineering projects and has improved the fault diagnosis efficiency of remote sensing satellite receiving system.
