Ultra-wideband based positioning system for applications in industrial environments

This paper deals with the topic of indoor ultra-wideband (UWB) localization systems in industrial buildings. This kind of channel is mainly characterized by high concentration of metal objects, which cause reflections, leading to strong multipath propagation. The model of the assembly hall is created and used in deterministic 3D wave propagation simulation tool. During the simulation, the mobile beacon travels along predefined route. The signal reception is carried out by stationary infrastructure consisting of several antennas with known positions. By using the simulated signals and adopted direct solution methods, the accuracy limit of the system is assessed.
