The Research Of Simulation Platform For Civil Aircraft Radio Navigation System

The aero-plane radio navigation system is one of the most important components for civil modern aircraft. The radio navigation system uses radio technology to measure navigation parameters, including Doppler Effect,radar principles and navigation station fixing.And it is widely used to guide the aircraft.The radio navigation systems provide important data to the aircraft systems, including the height of the aircraft,position, speed, and aircraft attitude, to guide aircraft flying along established routes safely.Radio navigation system has obvious advantages, such as independent of time and climate impact, simple device but extremely high reliability.However, the data that the system delivered mainly depends on carrier, and it is easily limited by the coverage of navigation stations, as well as radio propagation wave.But generally speaking, the advantage is still far greater than its limitations.The subject studies the mathematical principle and description of aircraft radio navigation system, mainly researches semi-physical simulation of the system,and based on modeling of complex systems theory, the theme establishes the mathematical model for navigation system as well as the method that how to implement what we proposed.The main work of the thesis contains the establishment of mathematical model for navigation system,the modeling for sub-module,ARINC429 protocol data transmission and reception,the design of system BIT(Built-In Test) and subsystems internal data transmission and navigation information calculation.The study and implement for aircraft radio navigation system provide useful and practical reference to engineering and theoretical research in the future.
