LOCOPROL

LOCOPROL ( Low Cost satellite based train location system for signaling and train Protection for Low density traffic railway lines ) was a project to study the inclusion of satellite navigation by rail from Europe with the aim of using on routes with low train density. It is intended as an extension of the ERTMS train protection. The Partners Project LOCOLOC examined here the cab signaling and speed control. LOCOPROL funded by the 5th Framework Programme of the EU. The project coordinator was responsible for Alstom.

Basics

Locoprol has taken the experiences of other systems, such as the operated since 1991 Euteltrac / OmniTRACS Qualcomm for satellite-based fleet management, followed by APOLO ( Advanced Position Locator ), ECORAIL (EGNOS Controlled Railway Equipment ) and parallel projects like InteGRail (2001-2003 ) of the ESA. Just as GADEROS (Galileo demonstrator Railway Operation System) for the study of satellite tracking in the ERTMS (project partner INECO, TIFSA, Railways Safety, ERRI, Aena, GMV Sistemas, Sener, NSL) LOCOPROL was funded by the 5th Framework Programme of the EU.

The project by Alstom (Belgium ), Honeywell Control Systems GmbH ( Germany ), INRETS (France) was supported, Alstom Transport (Italy ), Trasys (Belgium ), Alstom Transport (France), BPV ( Germany ), Septentrio (Belgium ), Reseau Ferré de France (France), Société Nationale des Chemins de fer Belges (Belgium ), Northern Jiaotong University (China ), European Road Transport Telematics implementation Coordination organization SCRL (Belgium ).

Continuation

The project officially ended in 2005, but results were continued in other projects. ESA has studied from 2006 RUNE ( Railway User Navigation Equipment ), the suitability for the Galileo (satellite navigation ) for " virtual beacons ". and the project GEORAIL UIC deals since 2004 with the use of location systems in rail transport. In the 6th Research Framework program of the EU are then SUNFLOWER ( accompanied by the GPS LOC SNCF ), GRAIL and M -TRADE contain, which ran until 2007. In England, the LOCASYS joined the LOCOPROL project, the more dependencies to 2009 examined, and in Belgium the LOCOPROL pilot line was further expanded with respect to the Trans Logistic project between 2007 and 2009 that examined the suitability of integrated transport. In use are eventually satellite systems in rail transport in France for example - the Tr @ in -MD SNCF supervised the transport of dangerous goods and Gedeon SNCF allows the cargo tracking the route network.

Similar projects are satellite-based command with the Nationwide Differential Global Positioning System ( NDGPS ) to be developed as part of the Positive Train Control in the United States by 2015. The ERTMS Regional system of Banverket is also a cost-optimized version of ERTMS for use on branch lines, but that still works without satellite positioning. For the 7th Research Framework Programme of the EU, the GRAIL -2 project of the GSA / ESA is suggested that the integration of satellite positioning in ERTMS further investigated.

Results

The results of LOCOLOC / LOCOPROL showed that the satellite navigation in urban areas is severely limited by lack of visibility of satellites. The project developed algorithms that could match the satellite signals with a one-dimensional flat route map so already two satellites is sufficient to ensure ( by six satellites for safe EGNOS measurement can 3, in certain cases 4 satellites fail ). However, the barriers of SIL 4 safety criteria were not met ( 98% of measurements outside the tunnel successfully ), but the test model was not conclusive for all dependencies of the system. The results have pointed out, however, that passive eurobalises are necessary in the area of breakpoints to counteract the lack of precision of satellite-based train location.

Since the EGNOS certification for safety-of -life applications in the course of 2010 is still present, the results of LOCOPROL could be subsequently checked again in a non- prototypical environment. By comparison, the North American Joint Positive Train Control Program is working there with two differential GPS receivers, connected to a inertial navigation system for bridging distances with weak satellite reception by dead reckoning navigation ( dead reckoning ). The developed with the Italian Ansaldo STS ITARUS -ATC also uses (mostly GLONASS) to ensure, in conjunction with distance measurement via wheel sensors and inertial measurement for changes in direction to ensure a high level of security for the Russian passenger satellite navigation based on the Russian KLUB- U command - it should be the Winter Games in 2014 used on the route to Sochi.
