为提高科学卫星有效载荷地面测试的准确性和效率,分析了国内外现有卫星地面电测系统平台及其应用,设计并实现了一个基于CCSDS 660.0标准的通用EGSE综合开发平台. 基于该平台分别设计并实现了空间用CCD相机的性能定标和星上科学数据处理单元(DPU)的功能验证实验. 结果表明,该平台具有很好的通用性与可扩展性,能够适应载荷的子单元、子系统以及系统的测试配置要求. 为国内EGSE通用平台的研制及科学卫星有效载荷EGSE平台化开发提供了参考.

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.
