The Civil Aviation Administration of Air Manage

On July 14, the Civil Aviation Administration Air Management Bureau organized the promotion of ADS-B (broadcast automatic related surveillance system) technology application research results and optimized adjustment work video conference. The meeting comprehensively summarized the main achievements of ADS-B technology in my country's air management applications, shared the research results of existing problems and its response measures, and judged the future development direction of ADS-B technology applications, and deployed the next stage of work. The representatives of the ADS-B technology application research working group made special reports on topics such as research results, pilot verification, and optimization adjustment.

Since the Civil Aviation Administration issued the "Comprehensive Promoting Implementation of ADS-B Air Pipe Operation Work Overall Plan", the empty pipe system has actively promoted the application and technology application of ADS-B air pipes and achieved major phases The second stage goals. Urumqi, Aksu, Harbin, Yantai, Lijiang and other regulations implement ADS-B control operations. The proportion of integrated applications in ADS-B in the air traffic control system has increased from 65%at the end of 2019 to 92%. The region provides surveillance and guarantee, and has provided continuous and stable supplementary alternative services when the radar exit service has promoted the dual improvement of safety level and operating efficiency. ADS-B assisted the operation of Chengdu-Lhasa, Yushu-Lhasa, and drove regional and local economic development. It provided ADS-B data sharing services for the Civil Aviation Administration, airports, airports, and civil aircraft manufacturing. The monitoring capacity of flight operations has been successfully achieved the enhancement and coverage of the comprehensive surveillance capacity of the South China Sea, entry and exit areas, and mountainous areas.

The ADS-B is the first to achieve the localization rate of all-system single-item projects in recent years, which has increased the localization rate of air management surveillance equipment in my country from 44%to 69%. The level of research and development and manufacturing capabilities of China's industry has laid a solid foundation for the global application of Beidou. The proportion of domestic aircraft's DO-260B versions has increased from 25.7%at the end of 2019 to the current 70.11%. With the continuous improvement of airborne modification rate and ADS-B application, ADS-B will further select security auxiliary functions such as consistency alarm, aircraft identification, instruction mid-term conflict warning, and flight number inconsistency/similar alarm and other security assistance functions. Play a positive role. The application of ADS-B is integrated in satellite navigation, communication technology, airborne equipment, and ground equipment. The integrated collaboration of planning, construction, and operation. The integrated cooperation in the industry has been fully practiced.

The ADS-B technology application special research working group adheres to the problem orientation, focusing on the first stage of ADS-B empty pipe operation in the early stage of controlling application, external environment, data analysis, and airborne equipment. Sumulatory, root analysis, simulation testing, improvement of research and development, pilot verification and other research work, and formulated a unified data output and packaging rules for the ADS-B ground station, innovating the effective time maintenance mechanism of the application data; for the ADS-B data center ( Station) Put forward the criteria and processing principles of ADS-B abnormal data, the recommendation standards of the ADS-B quality index in four operating scenarios; the optimization algorithm and flight plan for the fusion of multi-source surveillance data are proposed for the automation system of the air pipe automation system. Related logic, ADS-B and S mode data are optimized and adjusted to optimize the adjustment and adjustment of the entire business chain, such as the optimization of the control interface, which forms three major parts, 19 major chapters, 12 test verification
