Analysis of the Principle of VOR NavigationABSTRACTNowadaysw,with the development of aeronautical radio navigation technology,manyadvanced navigation equipments are applied in the field of Aeronautical navigation.As one ofthe short-range navigation systems,VOR system plays a very important role in the field ofaviation navigation.This paper mainly introduces the working principle of the vole system,putsforward the advantages and disadvantages of the system,analyzes the causes of inaccurate anglemeasurement,and gives some solutions.The VOR system determines the azimuth of the aircraftrelative to the north direction of the VOR ground station by comparing the phase differencebetween the variable phase signal and the reference phase signal.The vole system consists oftwo parts:the vole ground station transmits signals,and the airborne equipment receives,processes and displays signals.These systems are also gradually updated over time,from CVORto today's DVOR.DVOR overcomes some shortcomings of CVOR,but there are still somefactors that affect the measurement accuracy of DVOR.To solve the problems of vole system,we need to work together from the aspects of technology and management.Keywords:Navigation VOR Doppler之
