Microcontroller based simulation of the very high frequency omnidirectional radio range (VOR) system in aircraft

Abstract

As it is known, different navigation systems, such as Non-Directional Beacon (NDB), Automatic Direction Finder (ADF), Very High-Frequency Omnidirectional Radio Range (VOR), Instrument Landing System (ILS) and Distance Measurement Equipment (DME), are used for the aircraft to take off, travel and land safely. This study aims to motivate students, who educate in aviation electricity and electronics departments of aviation schools established to meet the needs of the aviation industry, to learning the microcontroller course better. To achieve this aim, the VOR receiver, which shows the aircraft's radial according to the VOR station from which receives its signal, has been simulated. Since the microcontroller to be used in simulation and the compiler to be used in programming the microcontroller may vary, only flow diagrams and basic calculations are given. In the simulations, it was seen that the phase difference between the reference and variable signals sent by the VOR station were correctly detected, and thus the aircraft could accurately determine the radial relative to the VOR station.
