EGNSS infrastructures and ARAIM technologies play an important role for the adoption of GNSS into Train Control Systems

The  RHINOS team, co-ordinated by Radiolabs,  with  DLR, the Universities of Nottingham, Pardubice, Stanford and with Ansaldo STS and Sogei have successfully completed the project – co-funded by GSA – bringing an important contribution for the adoption of GNSS in the train control application. Final results   verified with simulations and experimental data, demonstrated  that is possible to achieve protection levels in the range of 12 meters along the track and 5 meters for parallel track discrimination,  representing a 60-80% improvement respect to previous results.  An innovative two levels architecture with Advanced Receiver Autonomous Integrity Monitoring (ARAIM) has been developed and simulated  to detect and mitigate the Multipath  that is the greatest threat to the viability of GNSS for rail applications. These results are expected to contribute to the process of standardization and certification. (
