Abstract

The UWB D-DWM-PG3.6 is a standalone positioning system based on Decawave’s (now Qorvo) ultra-wideband technology. It is designed for local positioning without requiring satellite data systems, making it effective in areas with weak or unstable GPS signals. This study focuses on developing a method for reading and filtering data from the UWB system to obtain stable position parameters.  Outlier data are removed, and filtering by moving average helps to smooth and stabilize the position data. Experiments were conducted in a 40×30 m space to evaluate the method’s accuracy. The results show an average positioning error of 7.1 ± 3.6 cm, with a maximum of 26.9 cm under obstructed conditions. These findings highlight the potential for navigation applications in autonomous devices operating in enclosed spaces, such as warehouses and agricultural greenhouses, at a reasonable cost. However, the error magnitude indicates that the system should be integrated with ultrasonic sensors, recognition cameras, or laser technology to improve accuracy.
