Abstract:	Using present available satellite navigation systems is growing in thenon-safety rail applications like fleet management and passengerinformation systems. For safety-related applications, however, theaccuracy of train position, the service guarantee, the integrity aswell as Time To Alarm should be achieved by more advanced satellitenavigation systems like GALILEO. This paper gives a brief descriptionof the GPS, GLONASS and GALILEO systems. A supplementary mean toobtain satisfied accuracy of the GPS receiver for safety-relatedapplications is described by taking the example of the APOLO project.It is concluded that GNSS-based systems can be used as a dispatchingtool for automatic train position monitoring in the short term. In thelong term, however, more sophisticated real-time interlocking systemswith fail-safe architectures will be on the basis of the GALILEOsystem.
