| Abstract: | Eurobalises have been widely used for train positioning in ETCS and CTCS.In order to improve the precision of positioning,a large number of track-side devices have to be equipped,which would lead to high costs for construction and maintenance.Then the virtual balise solution is proposed,in which the high accuracy GNSS receiver and relevant software are combined to realize the function of the traditional balise,guaranteeing safety,improving positioning accuracy and reducing costs of construction and maintena... |
