In order to realize the rapid integration and testing of spacecraf, the concept and the application background and foreign early application status of SEDS，which is in SIOS of Consultative Committee for Space Data Systems（CCSDS）are analyzed. The layered architecture and the functions, service, components and protocols of the integrated electronic system are studied. Based on this architecture, the top-level application design, design example of telemetry acquisition and application extension of SEDS in the development of the Service and Protocol System are presented. This design was verified in software development, debugging, unit testing, integrated testing, confirmation testing and the results show that the application of SEDS will give a support to standardize the satellite onboard interface and shorten the cycle of the Service and Protocol System and even the entire spacecraft by Auto-generated code and data reuse in different stages.
