Satellite bus data analysis system

A satellite bus data analysis system comprises a data collection and storage module and a bus data analysis module. The data collection and storage module is connected with a satellite electronic system via a bus, collects bus data, and transmits bus data frames to the data analysis module. The bus data analysis module receives and then stores the bus data frames transmitted by the data collection and storage module, determines the format of the data frames, and compares the bus data with interval type parameters, equivalent change type parameters and hopping type parameters to determine current bus data. Compared with the prior art, different types of intermediate data can be stored in real time, convenience is provided for searching in future, the collected bus data is analyzed in real time according to the parameter models, and thus, the reason of fault of satellite electronic system can be found more accurately and timely.
