The EGNSS MATE project, led by Swiss Federal Railways (SBB), has developed and tested new map-assisted sensor fusion algorithms, using European GNSS (Galileo) and other sensor data to safely estimate train position, velocity and time information.

ERTMS moving block operations rely on continuous communication, via GSM-R or newer systems, and onboard train integrity monitoring.

The long-term goal, Wenz explained, is to introduce new positioning technologies such as GNSS, into the control command and signaling scheme of the European Rail Traffic Management System (ERTMS).
