Abstract
One of the most important ways to improve aviation radio navigation systems is to increase the accuracy of aircraft position-fixing. Among the factors affecting the accuracy of radio navigation systems is the signal-to-noise ratio, the magnitude and dynamics of which are the subject of this work. The assessment of the signal-to-noise ratio will theoretically improve the accuracy of aircraft position-fixing by applying adaptive filtering algorithms. The article presents the results of theoretical studies of the signal-to-noise ratio and the factors influencing its absolute value. An experimental installation for monitoring signals from air navigation support facilities is presented. To assess the changes in the signal-to-noise ratio, the results of recording and studying the signal of the Doppler VHF omnidirectional radio range (DVOR) at Irkutsk International Airport and the daily log of the signal-to-noise ratio for various GNSS satellites are presented.
