Abstract

The paper shows the architecture of a Location Determination System based on GNSS (GNSS-LDS), mainly focusing on the design of on Board Unit (OBU) installed on a train.The work is inserted in the scenario of introduction and application of space technologies based on the ERTMS (European Railways Train Management System) architecture, bundling the EGNOS-Galileo infrastructures in the train control system. It aims at improving performance, enhancing safety and reducing the investments on the railways circuitry and its maintenance. The algorithm core for determining the train location will be showed together with results of a campaign test acquired on a important highway (GRA: Grande Raccordo Anulare) around Rome (Italy) to simulate train movement on a generic track.
