Computer Simulation for Calculation of Expected Train Position at GNSS Signal Failure within a Railway Network Model

Abstract

The article describes the use of computer simulation for assessment of a rail vehicle in the GNSS signal failure situation in a railway network model. Attention is paid to a brief overview of the existing solutions in the field of rail vehicles localization on regional lines, and to the description of a multi-layer rail network model. The article further deals with identification of rail vehicles position within a railway infrastructure model with the use of the GNSS system focusing on regional lines. The last part introduces the experiments of assessment of future position of a rail vehicle in the GNSS signal failure.
