Real-Time Location with Ultra-Wideband (UWB): A Python-Driven Test Framework

This article presents a Python test framework for a Real-Time Location System (RTLS) based on Ultra-Wideband (UWB) technology. The author uses Decawave DW1000 modules and Raspberry Pis, implementing two-way ranging with custom Python code and testing system accuracy and stability. The article details the Asymmetric Two-Way Ranging technique and discusses hardware selection, software architecture, and potential problems such as power supply, interrupt handling, and RF performance. Test results show that the system offers high accuracy and stability under good line-of-sight conditions and maintains a degree of accuracy even with obstacles.
