New Systems for Telematic Applications in Railway Traffic

S. Bedrich, N. Lemke and S. Müncheberg

Abstract:	Due to the availability of precise satellite navigation systems, namely GPS (and in future Galileo), railway traffic, in particular the railway transportation sector, is facing a revolution in terms of flexibility of operations. Today, autonomous GPS receivers combined with a terrestrial data information exchange system, so-called telematics systems, are found in a vast variety of land transport applications, which are in most cases tailored to the individual needs of the vehicle or cargo operator. The technology is nearly mature in road-based transport, i.e. car, truck and cargo traffic. The railway sector was more reluctant in the past, but is more and more convinced of the advantages of this technology today, and requests arise to make profit of the telematics technology in railway transport, too. Kayser-Threde is active in this field since mid of the 1990's, focussing at that time on less demanding applications as wagon tracking and fleet management. Since 2000, efforts have been undertaken to solve also higher demanding problems in railway telematics, as they arise in safety-critical or high-density applications. Here, additional sensors like odometers, an inertial unit, a digital track map, etc. are grouped around a GPS receiver and supported by an integrated fault tolerant position solution software. The present paper gives an overview of the specific requirements of railway telematics and reports about Kayser-Threde's recent activities and high-end system solutions in this area.
