UWB-based Positioning System for Indoor Sports.

Information and communications technologies are increasingly present in sports’ execution, being implemented in a huge variety of tools used to improve player performances and/or the decision-making of referees. However, the position and movement of the players, being an essential information variable, is still not widely measured by current systems, especially at indoors and outside the high-competition. To address this, the present work focuses on the application of positioning techniques for indoor sports. In this way, a system employing Ultra-Wideband based radio-positioning is designed and implemented to locate players in real time. The performance of such system is then evaluated in a real environment, considering several trajectories with direction changes and followed in different conditions.
