Research on UWB Positioning Accuracy in Warehouse Environment

Abstract

This paper researches and solves the problems of NLOS(non-line-of-sight) existing in warehouse environment, which would result in poor accuracy using UWB board to position. On the basis of predecessors, this paper proposes and tests two methods, which would reduce the NLOS error conduced by occasional obscuring and fixed objects obscuring to channel. Experiments verifies the positioning results would achieve centimeter level accuracy. After the analysis and demonstration of experimental data, these methods can be applied to warehouse management and improve the informationization and automation level of the warehouse.
