Sensor Fusion of Ultra-Wideband and Bluetooth 5.1 for Precise Indoor Positioning
This paper presents a hybrid indoor positioning system that combines the high-precision distance measurement (Time of Flight) of ultra-wideband (UWB) with the directional angle estimation (Angle of Arrival) of Bluetooth 5.1 (BLE) via sensor fusion. As individual radio-based systems often reach their limits in complex e...
