Satellite based localisation systems (GNSS) – GPS, GLONASS and future Galileo – are widely used for non safety relevant applications in transport like passenger information or tracking and tracing of goods providing large economical and operational benefits. In all four domains of transport – road, rail, aviation and maritime – the usage of satellite based localisation for safety relevant applications – for example automatic driving and train control – would bring even more benefits but requires a certification. To apply satellite based localisation systems in safety relevant applications, the domain specific certification regulations have to be respected. In this paper, these regulations are analysed with a specific focus on the application of satellite based localisation systems in railways. This work is done within the project GaLoROI which has the target to develop a certifiable satellite based localisation unit for railways.
