This paper presents the implementation of an Angle of Arrival (AoA) estimation algorithm using FPGA technology as a part of a Smart Train Positioning System (STPS). The STPS takes advantage of the combination of different technologies and techniques, such as GNSS and the AoA of the GSM-R signals, to determine the real time train position. Furthermore, a complete software AoA system simulator has been implemented and used to validate the implementation of the AoA algorithm in the FPGA.
