Abstract: The extensive utilization of Global Positioning System technology has made our daily lives much easier. Compared to outdoor localization which requires an accuracy of just several meters, the complex indoor scenarios with dense multipath components need a better positioning performance. Ultra-wideband technology (UWB) improves the precisions ignificantly to centimeter level. The large bandwidth of UWB impulse radio (>500MHz) guarantees high time-of-arrival (TOA) resolution. However, even with such accuracy, the estimated indoor coordinate still deviates from the real location.The study of the range error dependency on distance helps refine the position estimation algorithm more effectively, hence enhance the reliability of UWB technology.
