High-Precision UWB Indoor Positioning System for Customer Pathway Tracking
This work presents an Ultra-wideband (UWB) indoor positioning system for tracking customer pathway. The position is located by the triangulation method and the Gauss-Newton method is utilized to ameliorate the location accuracy. Experimental results indicate that the Gauss-Newton method decreases the measured positioning errors at different distances. Consequently, this indoor positioning system can provide a high precision positioning performance in tracking customer pathway and determine which commodity is the nearest one to the customers.
