UWB-Based High-Precision Real-Time Positioning and Multi-Dimensional Visualization
Main Article Content
Abstract
This study presents a high-precision indoor positioning and multi-dimensional visualization system, named Virtual Positioning System (VPS), which utilizes Ultra-Wideband (UWB) technology. The VPS features an integrated architecture comprising portable Tag devices, fixed anchor units, a data collector called Position Box, and a web-based server. Tests conducted in various scenarios (office, factory, and retail environments) demonstrated that the system achieves a positioning accuracy of ±30 cm and provides high data stability.
The Two-Way Ranging (TWR) algorithm and Kalman filter minimize measurement noise, while IEEE 802.3-based communication prevents data loss. The 2D and 3D visualization modules provide capabilities for movement tracking, density mapping, and area-based analysis. In particular, 3D visualization enhances operational awareness by providing depth perception in multi-story buildings or metal-dense environments. The VPS is well-suited for future developments in terms of energy efficiency, signal stability, and visualization performance, adding value to industrial, corporate, and security-focused operations.
