Research on Digital and Automatic Test Technique for Networking Satellites

随着各类卫星星座计划的提出和部署,航天卫星数量的逐步增加,传统的卫星研制模式已逐渐不能满足卫星快速发射需求,为缩短卫星研制周期,卫星批量化、自动化测试手段逐渐成为新形势下卫星研制的关键一环;面向当前微小卫星高密度快速组网应用的需求,结合批产化卫星技术特点,研究了一种适用于组网卫星的数字化和自动化测试技术;对卫星综合测试系统架构进行优化,可满足多星批量化及并行测试;在卫星综合测试系统中增加自动化测试功能,可通过在线配置自动化序列实现卫星自动化测试;研发了一种数字卫星仿真测试平台,可用于卫星单机产品齐套前整星功能开发、测试等;克服了传统卫星研制周期长、测试过程数据判读和数据处理难度大以及重复性工作较多的缺陷。

With the proposal and deployment of various satellite constellation plans and the gradual increase of the satellites,the traditional satellite development model has been unable to meet the rapid launch requirement of the satellite.Under the current situation,the batch and automatic testing methods for the satellite have gradually become a crucial step to shorten the satellite development cycle.Focusing on the demands of networking satellites high-density rapid launch,combining the technique characteristics of the batch satellites,a digital and automatic testing technology is presented to be suitable for the networking satellites.The architecture of the satellite comprehensive test system is optimized to meet the multi-satellite batch and parallel testing;the automatic test function is added to the satellite comprehensive test system,and the automatic satellite test can be realized by the online configuration of the automatic sequence;A digital satellite simulation test platform is developed,which can be used for the development and testing of the whole satellite function before the stand-alone products for the satellite are completed.Compared with the presented methods,it overcomes the defects of long period of the traditional satellites,difficult data interpretation and processing in the test process,and many repetitive tasks.
