摘要

The paper deals with possibility of integration of GNSS as a source of position information into the railway signalling system. It is focused on the use at secondary rail roads where it should substitute conventional ETCS signalling system. The description of the use of GNSS for safety critical applications is presented in the first part of the paper concerning possible influence of GNSS to the failures of the system and its investigation with the use of information or system redundancy. Design of a suitable GNSS receiver based on Software Defined Radio Concept (SDR) was realized in the frame of the project of the Czech Ministry of Transport. The various possible realizations of SDR and aspects of their use are analyzed. The design of the SDR based GNSS receiver for railway applications developed at the Czech Technical University is presented in the end of the paper.
