Effect of Base Station configurations and complexity on the accuracy of ultra wideband localisation

This paper presents experimental work on 3D localisation using different Base station configurations. The two Base Station (BS) configurations proposed (L shape and Mirror Based) use only 3 BS´s and are able to achieve good accuracy in cm range in 3D. Time of Arrival and peak detection algorithms are used to find the position of the target. Results show that the configuration of base stations directly affect localization accuracy. It is observed that the average localization accuracy of the L shape configuration is in the range of 3-5 cm and for mirror based configuration is around 2 cm for x and y axis and 5 cm for z axis. Average Directional accuracy achieved is approx 1 to 3 degrees for both azimuth and elevation angles.
