DIRECTIONAL INFORMATION VOR SYSTEM IN THE ACOUSTIC MEDIUM

Abstract

The article describes design of didactic aid. Main reason is visualization and theoretical explanation of making course information of system DVOR. First par is focused to theoretical background of ground station of system DVOR – which signal is used and how they are generated. Second part is focused on aircraft part of system DVOR – receiver. Theoretical background provides main starting point for design an electronic receiver of DVOR simulator. DVOR transmitter is built as another master thesis. This simulator uses for his function acoustic waves. In real. Frequency used in DVOR is too high for hearing, so it was a good choice use acoustic waves. Acoustic waves are affected by Doppler effect same as radio frequencies, so we can use them for simulation of DVOR system. DVOR transmitter transmits reference signal with amplitude modulation and frequency modulated variable signal. From this signals we can get course information as real DVOR system. This receiver is supplement to DVOR transmitter and together makes didactic aid of complete DVOR system.
