Design of big data processing system for spacecraft testing experiment

The ground and in-orbit testing experiment of spacecraft are of great significance to the development of China's space industry, and processing the data of testing experiment is an indispensable part in it. In order to solve the problem of large data volume, complex data structure and long time needed for analysis in the testing experiment of spacecraft, a big data processing system of testing experiment is designed based on the mainstream big data processing technology. It stores the test data in the distributed file system of the computer cluster, and uses the memory computing technology to realize parallel processing of the experimental data. This system can greatly reduce the time needed to process experimental data, improve the efficiency of the spacecraft testing experiment, and has a good application prospect in the field of spacecraft test.
