Research on Heterogeneous Model Exchange and Hierarchical Integration for Civil Aircraft Navigation

Precise navigation is the key technology of civil aircraft flight safety. Considering the problems of low quality and poor interactivity of navigation data transmission of aircraft, this paper attempts to construct a CPS theoretical framework of “architecture hierarchy integration-model heterogeneous collaboration” of the navigation system. Combined with the characteristics of a multi-domain physics-information model, an architecture hierarchy integration, heterogeneous model exchange and data integration for system engineering is proposed. Results show that the simulation results are in good agreement with the measured data, and the guidance deviation is within the error range. This method can effectively analyze and process the mapping relationship between navigation data and aircraft spatial position information and realize the accurate identification of motion trajectory and prediction of action route of civil aircraft. It expands methods and tools for solving the problem of integrity monitoring of navigation systems and can provide data support for the establishment of air-borne navigation data standards and application specifications.
