Ray-tracing model of satellite to aircraft communication in aeronautical satellite communication system

In aeronautical traffic systems, reliable propagation simulation and modelling are absolutely necessary to achieve safe aeronautical communication. This paper applies the numerical ray-tracing method on propagation modelling to model satellite-to-aircraft communication in aeronautical satellite communication systems. The objective of this paper is to simulate the power loss and time delay of the received signal on the aircraft antenna. Ray-tracing models are designed to simulate data like power and time delay of direct and diffuse signals, as well as Doppler shift and carrier-to-noise ratio of received signals along the aircraft path.
