Abstract

This paper presents an innovative method of locating airplanes, which uses only voice communication between an air traffic controller and the pilot of an aircraft. The proposed method is described in detail along with its practical implementation in the form of a technology demonstrator (proof of concept), included in the voice communication system (VCS). A complete analysis of the performance of the developed method is presented, including the results of simulation and measurement tests in real conditions. The obtained results are very optimistic and indicate that the proposed solution may constitute an alternative method of locating aircraft in emergency conditions, i.e., a backup solution in the case of failure of other positioning systems.

Highlights

Many systems providing the position of the aircraft in various phases of its flight are used in the world
It was decided to conduct research only inside the area limited by radio stations because, as it turned out during the experimental verification, transmissions originated from planes outside the area were rarely received by at least three ground stations or the signal-to-noise ratio was too low in distant stations to obtain reliable position indication
The east north up (ENU) system was adopted here, the origin of which coincides with the location of the first station, the XY

Summary

Introduction

Many systems providing the position of the aircraft in various phases of its flight are used in the world. The aviation radio navigation systems in use can be divided into two main groups: passive systems, in which the aircraft relies solely on the received information in the navigation process, and active systems, in which the aircraft participates both in receiving and transmitting navigation information. The first group of systems includes mainly [1]: . The second group of aviation radio navigation systems includes mainly: Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. Instrument landing system (ILS); Microwave landing system (MLS); VHF omnidirectional range (VOR) and Doppler VHF omnidirectional range (DVOR); Non-directional beacons–automatic direction finder (NDB–ADF); Global positioning system (GPS).
