Abstract: In addressing the practical problems currently faced by spacecraft testing a multiple types of data access method is introduced,which is designed to tackle issues such as improving telemetry real-time decoding performance,accessing satellite payload data,processing telemetry for both the primary and secondary satellites,and handling high-speed telemetry processing.The design concept,implementation methods,and application scenarios of the scheme is provided.Through practical applications,it’s verified that through the method，the testing time was effectively reduced,the data interface and the maximum decoding efficiency were expended，and the automation level of satellite testing was enhanced.Scalability,low-coupling,and high-efficiency data processing,which gives the method significant advantages.

Key words: Spacecraft electrical performance testing, Telemetry real-time performance, Multiinterfaces, Distributed, Automated testing
