| Summary: | A complete impulse-based ultrawideband localization demonstrator for indoor
applications is presented. The positioning method, along with the method of positioning error
predicting, based on scenario geometry, is described. The hardware setup, including UWB
transceiver and time measurement module, as well as the working principles is explained. The
system simulation, used as a benchmark for the quality assessment of the performed
measurements, is presented. Finally, the measurement results are discussed. The precise analysis
of potential error sources in the system is conducted, based on both simulations and
measurement. Furthermore, the methods, how to improve the average accuracy of 9 cm by
including the influences of antennas and signal-detection threshold level, are made. The
localization accuracy, resulting from those corrections, is 2.5 cm. |
