Abstract:

According to International Civil Aviation Organization required navigation performance (RNP) standards and regulations, a model-based system engineering method is proposed to design and verify the architecture of aircraft navigation system. According to the RNP operation requirements of civil aircraft in the terminal area, combined with the architectural characteristics of typical foreign civil aircraft, the requirements analysis, function analysis and design synthesis of the architecture design of domestic civil aircraft navigation system are completed. By studying the adaptation scheme of the navigation sensor in the terminal area, a multi-source navigation information fusion model is established. Finally, a system modeling language combined with simulation software model co-simulation mechanism is used to verify the navigation system architecture mod.

Key words: model-based systems engineering (MBSE), required navigation performance (RNP), architecture design, information fusion, joint simulation
