Seamless location based service in the railway sector using GPS and IMES

As train stations have become increasingly convenient as they grow bigger and more multifunctional, both in urban and rural areas in recent years, there are also challenges to provide users with easy-to-understand guidance and information in increasingly complex indoor spaces. This paper presents the results of a demonstration experiment using the Global Positioning System (GPS) and the Indoor Messaging System (IMES) that is compatible with GPS, and which can obtain positional information accurately indoors, offering a future outlook for the system in the railway sector.
