Abstract

As smart phones are rapidly spreading these days, researches are increasing to provide position-based services for indoor spaces. Each of these technologies has both strengths and weakness. Even UWB, which has the most precise, wide and dynamic positioning capability, requires infrastructure such as transmitter and receiver like Bluetooth, and in order to apply the fingerprinting technology to complement the RSSI of Wi-Fi, it is required to map a reference point that divides the entire space to be applied. This paper proposes a plate technique that improves low accuracy and the large position estimation deviation against existing BLE based RSSI technique. In addition, we propose an algorithm that enhances the accuracy and efficiency of indoor positioning system by integrating the PDR technique using IMU data of terminals. As the result of this study, it is confirmed that the accuracy of direction and moving distance, with positioning error within 2.2m, is applicable to indoor navigation system for the very large spaces such as airports and stadiums.
