Abstract:
This study is based on those data gathered on a 450m-long railway with a VRS GPS. In addition, certain location data on a railway were gathered through three 'Continuous VRS GPS' measurements and one 'Stop & Go VRS GPS' measurements while a railway-maintenance vehicle with GPS receivers mounted on its left & right sides was moving, Based on these location data, an average inter-rail space was analyzed. As a result of the analysis, the inter-rail space ranged from 1480mm to 1530mm. Based on the standard design dimension of an inter-rail space equal to 1,500mm and the average VRS GPS accuracy of ±3cm permissible in South Korea, the range was acceptable. Furthermore, if the center of a GPS receiver is placed over the vertical line of a rail center, more accurate location data on the railway could have been gathered.
