Abstract :
Positioning systems have gained importance in situations where various location-based services have been installed. Although the combination of Wi-Fi positioning with inertial navigation is considered to be accurate for indoor use, it is important to avoid increasing the error when using estimated positions for location-based services. In this paper, we propose a positioning system that combines several positioning methods with different characters to avoid increasing the error. Demonstration experiments that show the effectiveness of the proposed system in an exhibition hall are also described.
