摘　　要：随着光学遥感小卫星业务不断增长,基于刀片服务器的传统数传基带测试系统已无法满足卫星批量研制测试需求。为此,文章设计了采用机架服务器+光纤交换机的数传基带测试系统,实现小型、通用、可扩展的硬件架构,支持高效、高速的数据处理、存储和交互,与传统系统相比,体积、功耗、质量显著减小。为适应新硬件架构,将原有各数传基带测试软件进行混合并行处理和动态负载均衡设计优化,可以稳定、可靠地提供并行实时数传基带测试功能。该系统具有集成度高、通用性好、测试时效性高等特点,在多型批量化生产的光学遥感小卫星研制过程中测试应用效果良好。With the continuous growth of small satellite business of optical remote sensing, the baseband test system of data transmission based on blade server has been unable to meet the requirements of the satellite batch development. Therefore,a baseband test system of data trans-mission using rack server and fiber switch is designed. It can realize a small, universal,scalable hardware architecture？ which can supply efficient high speed data processing, storage and interac-tion. There is a significant reduction in size, weight and power consumption than before. In order to adapt to the new hardware architecture, the original baseband test software of data transmis-sion is optimized and designed by mixed parallel processing and dynamic load balancing, which can make these software stably and reliably offer parallel real-time baseband test of data trans-mission. The system has the characteristics of high integration, good generality and high timeli-ness, and has good application effect in development of multi-type small optical remote sensing satellites produced in large scale.
