A High-Precision UWB-Based Indoor Positioning System Using Time-of-Arrival and Intersection Midpoint Algorithm

This study develops a high-accuracy indoor positioning system using ultra-wideband (UWB) technology and the time-of-arrival (TOA) method. The system is built using Arduino Nano microcontrollers and DW1000 UWB chips to measure distances between anchor nodes and a mobile tag. Three positioning algorit...
