GRAIL-2: Enhanced Odometry Based on GNSS

Following the introduction of the Satellite Navigation technology (GNSS) in the railway domain started with past European initiatives, the objective of GRAIL-2 is to define, develop and validate a GNSS application in high-speed railway lines, focusing at a concrete market and aiming at offering a product close to the customers within the European Rail Traffic Management System framework (ERTMS) paradigm. The proposed system is based on Enhanced Odometry. In the frame of the 7th Framework Programme, 2nd Call, the GRAIL-2 consortium has been granted with European funds to start rolling out the strategy, defined in the precedent project, GRAIL, for a smooth integration of GNSS into control and command applications and particularly within the European Train Control Systems (ETCS) framework. The GRAIL-2 Consortium is composed of 10 participants from 8 EC countries. A prototype is being developed and it will be tested to demonstrate the concept in a real environment. Details on the concept, activities performed and first results are presented in this paper. The GRAIL-2 project is managed by the European GNSS Agency (GSA) in the name of the European Commission (EC).
