Analysis of airworthiness requirements of Beidou-3 airborne equipment only used for tracking

With the opening of Beidou-3 navigation satellite system service, the relevant airworthiness standard of Beidou-2 cannot meet the requirements of the current application scenarios of airborne equipment, which seriously restricts the application process of Beidou in the field of civil aviation. It is urgent to carry out the research and formulation of the corresponding standard of Beidou-3. The primary goal of Beidou’s implementation in civil aircraft is to be “used for aircraft tracking only”. In order to achieve this, the distinction between Beidou-2 and Beidou-3 is examined, and a proposed modification plan is presented. In order to provide standard support for equipment development and airworthiness certification, the index revision scheme is put forward according to the equipment configuration, and the approval elements and compliance method suggestions are formed. This is done by taking into account the airworthiness safety and the application scenario of airborne equipment, combined with industrial practice. The key parameters such as equipment antenna gain and satellite visibility are simulated and analyzed to verify the correctness of the revised technical indexes. © 2024 Beijing University of Aeronautics and Astronautics (BUAA).
