거리 오차를 고려한 KRTCS 열차 위치 산출 방법

Various researches are required to ensure train location accuracy because train location calculation and report take important responsibility for driverless mode. In order to ensure credibility for driverless mode, KRTCS (Korean Radio-based Train Control System) onboard system calculates train location based on pulse signals from TG(Tacho Generator) and compensates distance error that is occurred through the train location calculation process by detect tags installed at specific distance. In this paper, the method to improve train location accuracy will be studied by reducing distance errors, occurred by accuracy of TG, on the process of location calculation and checked distance errors between the system applied location error compensation algorithm and none applied system.
