Positioning model design using beacon and geomagnetic sensor of smartphone

Abstract

As the indoor location service is growing, its related studies based on ZigBee, UWB, or Beacon are actively done. Indoor location requires higher accuracy than that of outdoor since the traveling distance is relatively shorter. But accurate user location is not easy to acquire due to such problems as fading, inter-floor interference or sensitivity of the signal receiver. Therefore, we are using the triangulation by RSSI of BLE Beacon to establish the initial user location and the Geomagnetic Sensor based PDR of Smartphone to determine the user location in this study.
