This paper introduces the design and implementation of a correlation automatic interpretation testing system based on FTA. By analyzing the current situation of satellite comprehensive testing, the urgent need for automated testing of real-time interpretation of high-speed data transmission and rapid positioning of abnormal results is proposed. The system design scheme is specifically introduced, and the composition of the automatic interpretation system is explained. The functional characteristics of the interpretation information configuration module, correlation interpretation algorithm module, fault tree positioning module, and abnormal data extraction module are explained in detail; We also analyzed the practical effects of system implementation on improving testing efficiency.
