Concept of vehicle autonomous localisation for railway application

The presented paper shows an innovative approach to a vehicle autonomous localisation system for railways, providing cost-efficient position information for various safety- or non-safety-related systems especially for protection systems on non-equipped secondary lines. This is the main focus of a project called "DemoOrt" which consists of developing a platform with an onboard, autonomous and vehicle-autarkic technology, a reference measuring platform and safety analysis methodology. This approach integrates and uses available as well as innovative technologies with the main focus on satellite based positioning (GPS, GALILEO and EGNOS)
