Abstract: To improve the efficiency and accuracy of spacecraft payloads testing, a CCSDS 660.0 standard compatible EGSE integrated development platform is proposed. Testing systems based on the platform were developed for the calibration of a CCD detector and the function verification of a high-speed data processing unit for a spacecraft instrument put under study. Test results show that the platform can be adapted to meet the requirements of assembly, subsystem and system level tests. The platform provides reference for the later project phases and other projects.
