Study of Ultra wideband localisation techniques using various monitoring configurations

This paper presents a study of Ultra wideband 3D positioning in terms of a compact UWB antenna and three different base station configurations. Time of arrival and first peak detection algorithms are used to estimate the position of the mobile station. Also spherical coordinate system is used to find the direction of the target. A comparative study is done between the three base station configurations namely cube shape, Y shape and L shape in terms of accuracy of location detection and compactness. Results show that the configuration of base stations directly affect localization accuracy. It is observed that the localisation accuracy of the cube shape configuration (1 cm) is better than Y and L shape configurations (4 cm) while for directional azimuth and elevation angles estimation Y and L shape configurations (1° & 1°) are better in comparison with cube shape (2° & 6°).
