Airborne Test Data Processing and High-Speed Transmission Technology Based on 5G Private Network

Flight test data processing and transmission are vary important links in flight tests, and improving the efficiency of data processing and transmission is an important requirement for flight tests. Based on the 5G dedicated data transmission network for flight tests, this paper designs an airborne test data processing and high-speed transmission system architecture. First, the real-time processing and real-time storage of airborne test data are realized through high-concurrency multi-core real-time data processing technology, and then the parallel processing of multiple flight test subject data is realized by subject data time positioning and parameter alignment technology. Finally, the data size is reduced by data compression technology, and the stable and reliable transmission of test data is realized by combining data segmentation and verification technology. The real-time processing and high-speed transmission system of test data based on 5G private network realizes the goal of automatically connecting to the 5G private network to transmit original data and result data after the aircraft lands, which greatly improves the efficiency of flight test data processing and transmission and promotes the progress of flight test data processing technology.
