Study and Mitigation of Platform Related UWB Ranging Errors

Abstract

Ultra Wideband technology has been presented as a precise and accurate solution for wireless ranging. However, the noise and errors created from the low-cost, off-the-shelf UWB devices have been a challenge. Therefore, a comprehensive characterization of these errors is required for these devices to work more efficiently in real applications. This paper will cover the characterization of errors in different environment and configurations, a zscore-based error estimation and correction method for LOS scenarios, and evaluation of its performance. The result shows errors with a maximum mean of 5cm after the proposed correction.
