Title: POSITION DETECTION DEVICE AND POSITION DETECTION SYSTEM
Abstract:
Provided is a technique for using GNSS to detect the position of a train with high precision and accuracy. An on-board device (20) performs GNSS verification when calculating the position of a train on the basis of GNSS information of a first GNSS unit (15) and a second GNSS unit (16), and performs an absolute position sensing process in which GNSS speed information is used when the verification is successful. When a vehicle (10) is positioned within a prescribed range from an above-ground device (60), the on-board device (20) acquires GNSS error information from the above-ground device (60) and reflects said information against the position information detected by the first GNSS unit (15) and the second GNSS unit (16).
