Abstract

In this work a complete Ultra-Wideband localization demonstrator for indoor applications is presented. The hardware setup, including UWB transceiver and time measurement module, as well as the working principles are explained. The positioning method, along with the method of positioning error predicting, based on scenario geometry, is described. The system simulation is presented, that is used as a benchmark for the quality assessment of the measurements performed later on. Finally, the measurement results are presented and discussed. The precise analysis of potential error sources in the system is conducted based on both simulation and measurement. Furthermore, suggestions how to improve the achieved average accuracy of 3.6 cm are made.
