| Outline of Final Research Achievements |
Though positioning systems using satellites has been well used in the outdoor environment, the indoor positioning using satellite cannot be realized since the satellite signal is not available. This research has established an accurate indoor positioning method using three-beam beacons, where the terminal estimates its location only from the signal strength information. We realized the array antenna feed network for multi-beam excitation, and fabricated beacons having the developed feed networks. The receiving terminal estimates its directions from multiple beacons, and its location is calculated by using triangulation technique. This study revealed the accuracy of the newly developed technique is 0.7 m at 50 percentile value, which is significantly better than the conventional technique.
