Railway High Integrity Navigation Overlay System

The RHINOS work programme includes the investigation of candidate concepts for the provision of the high integrity needed to protect the detected position of the train, as required by the train control system application. The EGNSS (GPS and GALILEO) plus the SBAS constitute the reference infrastructure that is available worldwide. In addition to that, local augmentation elements, ARAIM techniques and other sensors on the train are the add-on specific assets for mitigating the hazards due to the environmental effects which dominates the rail application.
RHINOS will be developed through an international cooperation with the Stanford University researchers that have been involved in the aviation application since the birth of the GPS. They have indisputable knowledge of the GNSS performance and high-integrity applications. The ambition is a positive step beyond the proliferation of GNSS platforms, mainly tailored for regional applications, in favour of a global solution. RHINOS would release the potential benefits of the EGNSS in the fast growing train signalling market

ION GNSS+ 2016 - Track Constrained RTK for Railway Applications

Category: News Created: Monday, 26 September 2016

This contribution deals with the integration of the GNSS technology into the ERTMS framework. Particularly, the hint of this work is the design of an algorithm that exploits carrier phase raw observation to determine, among a set of parallel tracks, which is the one the train is lying on. Making this functionality be compliant to SIL4 requirements is more challenging than the positioning long the line due to the reduced inter distance between the tracks. The track discrimination issue is then solved by explicitly taking into account that the train is constrained to lie on a track.
