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.

GNSS is expected to revolutionize train control systems by providing an efficient alternative to determine the train position along the track. However, GNSS is particularly vulnerable in the rail environment because of the presence of multipath in stations and at many locations along the track. Therefore, particular attention must be placed in assessing and evaluating multipath errors introduced by GNSS when using GNSS to replace physical balises with virtual balises.

In this paper we investigate a multipath detector based on the analysis of the double differences of pseudoranges provided by two GNSS receivers on board a train making use of two different antennas. 

This research, is developed within the RHINOS project co-funded by the GSA that is contributing to the roadmap for introducing GNSS into the European Train Management System (ERTMS).

 A Method for Multipath Detection and Mitigation in Railway Control Applications


Radiolabs presents the RHINOS project at InnoTrans 2016

Category: Events Created: Tuesday, 20 September 2016

Radiolabs, will be showcase RHINOS research project at InnoTrans – the leading international trade fair on Railways transport technologies and products that will take place by 20th to 23th September in Berlin, Germany. 

RHINOS, an H2020 GSA Galileo 3 project, aims to exploit GNSS infrastructures by developing augmentation techniques to achieve high integrity train localization to be used for train control systems on a world-wide basis. The consortium, led by Radiolabs involves major international research centers on GNSS as DLR in Germany, Nottingham University in UK, Stanford University in the USA and Pardubice University in Check Republic putting together a team of more than 30 experts on GNSS. The RHINOS presentation will be available at the GSA Stand.
