In recent years, railway station has changed into a complex station connecting with other routes, so there are many difficulties for railway station users to find their destination in the railway station. Especially, the mobility handicapped has difficulty in finding a destination point. Accordingly, a variety of services for improving mobility are required within the stations of railway station users including the handicapped, these services basically require the indoor positioning technology of the railway station. In this paper, the applicability of the fingerprinting method based on the measurement of the geomagnetic field strength, which is the most economical and accurate method among the methods for indoor positioning in the railway stations, is analyzed through experiments. Experiments were carried out in the platform section and the waiting room section of the metro station with two floors underground, and In order to confirm the change of the geomagnetic signal according to the running of the train, various cases such as the case where the train entered the platform, the case where the train was not at the station were measured and et al. Through these experiments, this paper confirmed that the fingerprinting method based on the geomagnetic field signal, which is widely used in the general industry, is applicable to the indoor positioning of the railway station.
