An UWB-Based NLOS Indoor Positioning System

This paper presents an UWB-based non-line-of-sight (NLOS) indoor positioning system, which includes a few specific positioning micro-base-stations, a mobile tag to be located and an edge algorithm server. The micro-base-station and the mobile tag have same hardware mainly consisting of a Decawave's DW1000 IC, which is an IEEE802.15.4-2011 UWB compliant wireless transceiver module. The edge algorithm server is implemented with Nodejs and is located at a position close to a micro-base-station. This positioning system can provide high-precision real-time positioning for a mobile target. Experimental results are provided to illustrate the validation of this positioning system.
