Human Real Time Localization System in Underground Mines using UWB

This work proposes an improved Real Time Localization System using UWB technology, for people and asset tracking in a closed environment, particularly in underground mines. The UWB technology has demonstrated a very good performance with a localization error margin below 41 centimeters. The main objective of this work was to develop an affordable, easy to use, and scalable localization system to detect people in underground mines that allows fast location and rescue in case of disaster. It can also improve the mine productivity under normal conditions. Different tests were carried out in mines and urban buildings to validate the design and evaluate the error margin. The test in an underground mine was done at “Casposo Mining”, which is located in the town of Calingasta, San Juan province, Argentina. Finally, an autonomy of 25 hours of continuous used was achieved using a 2000mAh battery.
