Design Analysis of a Hyperbolic Landing Navigation System for Aircraft

Abstract

Radio navigation is widely used nowadays, especially to precisely estimate aircraft position during the approach and landing phase of flight. However, it is challenging to ensure the accuracy of aircraft navigation using a transmission channel that changes rapidly due to noise and interference. To increase the safety and reliability of aircraft in the approach and landing phase, a hyperbolic landing system is proposed as a non-autonomous system. The main goal of this paper is to analyze the mechanism of radio signal propagation between the transmitters and receiver of a novel hyperbolic navigation system that uses the TDOA method. The paper evaluates the effects of the radio channel environment on the proposed system in the landing phase of flight. The theoretical analysis is verified by MATLAB simulations.
