철도차량용 열차정밀측위장치 개발을 위한 요구사항 도출

초록

Now, for the continuous location detection of train, The method which the moving distances of vehicles are verified using an odometer mounted within train, is used generally. There are some issues that the train's positioning errors are accumulated as the moving distances increase. To solve this problem, it is required to apply a variety of positioning sensors and to comprehensively deal with the informations of sensors. Therefore, in this paper, we analyze the trends of positioning technology for train being applied nationally and internationally, and derive the design requirement of precision train-borne positioning system applicable to the environments for general railways and high-speed railways.
