Abstract
We think the indoor navigation system to be necessary in common places, a department store, a supermarket and so on in the future. We showed the way to measure the position and the direction with arrayed IC tags and two antennas without other sensors. This paper describes applying an indoor navigation system by the technique to a real environment. IC tags, which store x-coordinate, y-coordinate and area number, are regularly laid between a floor made of reinforced concrete and tile carpets. The IC tags are read by a reader system with two antennas. The navigation algorithm utilizes the Dijkstra method that is a shortest path program. By the system, we succeeded in indoor navigation with the speed at about 7km/h.
