Abstract

Today, it is common for trains to incorporate autonomous positioning systems based on geo-location technologies similar to those used on road transportation. These positioning systems represent a cost effective solution for railway companies operating in not evolved regions. Furthermore, these positioning systems can enhance the reliability of positioning systems based on the occupation of the tracks (which are most used in the most developed regions). Autonomous positioning systems calculate the position of the train, but the position has to be sent from the train to the control center. GPRS/3G mobile technologies and WiFi radio technologies are the most common technologies for transmitting the position to the control centers. These technologies do not guarantee 100% coverage in certain areas such as tunnels or mountainous regions. This paper presents the results of the tests on an autonomous positioning system to add a new communications technology in order to increase its coverage. This technology is TETRA, which is a radio technology that has been traditionally used for voice transmission, but it can be a good complement to GPRS/3G when there is no coverage.
