Improved UWB-based indoor positioning system via NLOS classification and error mitigation

Non-Line-of-Sight (NLOS) conditions in indoor positioning systems significantly degrade positioning accuracy. Although Ultra-Wideband (UWB) technology is renowned for its high precision in Line-of-Sight (LOS) environments, under NLOS conditions, positioning errors typically exceed 30 cm. To address...
