The article presents the characteristics of major European projects concerning the use of signals obtained from the GALILEO system to determine the position of a train on a railway line. It also presents the possibility of using a differential version of the GPS system to increase the accuracy of determining the train’s position relative to railway infrastructure elements.GALILEO in rail transport is intended for linking control and supervision functions as well as increasing safety based on existing ERTMS/ETCS systems. It can also be used to ensure high stability of server systems [1] and power supply systems [5]. The high safety requirement in the railway sector can be met by using signals obtained from the GALILEO navigation system in conjunction with other sensors installed on traction vehicles, such as odometers, balises, or gyroscopes. The introduction of satellite navigation into the European railway system (…)
