Projects

RailSAT

Status date: 29 June 2017

The objective of the RailSAT project is to assess both the technical feasibility and commercial viability of sustainable operational services that enhance the current practices of monitoring railway track geometry and the surrounding environment by using satellite data. Earth observation, Interferometric Synthetic Aperture Radar (InSAR) and satellite navigation data are used to achieve this objective.

EOMST

Status date: 23 January 2017

The EOMST system developed by 21Net enables Internet services on board high-speed trains. The system uses multiple communication technologies to access the internet: cellular, WiFi and satellite. A Mobile Access Router manages the links  depending on their availabilities. 

SBS-RailS - Space Based Services for Railway Signalling

Status date: 28 October 2016

The Space Based Services for Railway Signalling feasibility study is dedicated to investigate how an integrated satellite navigation and satellite communication solution can complement  the Level 2 European Rail Traffic Management System (ERTMS).

Satellite navigation systems can be integrated with the on-board and wayside signalling systems to guarantee the required level of safety (Safety Integrity Level - SIL4) that is today provided by the existing train detection systems, while satellite communication systems can complement or even replace terrestrial communications.

Signal Processing Techniques for the Integrity of Navigation for Land Users (INLU)

Status date: 24 October 2016

INLU is a versatile testbed for integrity algorithms for land users (including railway users). It includes signal and threat generation capabilities at sample level, a versatile software receiver which allows combining various acquisition, tracking, PVT, multipath mitigation, consistency check and integrity algorithms, and means for analyzing the integrity performance of the algorithms under test.  Part of the activity is dedicated to assessing the integrity performance of algorithms in the railway environment for application in satellite-based train control systems.

RAILSAFE - Innovative Satellite-based Position, Navigation and Timing Concepts for New Railway Safety of Life Applications

Status date: 24 October 2016

The RAILSAFE project is aimed at exploring how different safety-enabled GNSS Augmentation techniques (such as SBAS, GBAS or RAIM) can be used or adapted to be used in the railway domain, thus fostering the adoption of GNSS technologies in a wider range of applications and contributing to the creation of the aforementioned business opportunities, as an input to a GNSS roadmap for railways.
