Accuracy Evaluation Techniques of train position detection using GNSS

Abstract

Maintenance or renewal of track circuits detecting train positions is heavy burden for a rail operator. Using Global Navigation Satellite System (GNSS) is one of methods which a train detects its position by itself and would be replacement of track circuits. It is required a preliminary evaluation for the accuracy of train detection position using GNSS on actual railways expected for application of GNSS. We are considering evaluation techniques for the accuracy of train detection position using GNSS.
