In this paper, a novel system consisting of small and lightweight measurement transponders and a number of fixed base stations is introduced for precise measurement of the local position of moveable targets in three dimensions.Abstract:
Precise measurement of the local position of moveable targets in three dimensions is still considered to be a challenge. With the presented local position measurement technology, a novel system, consisting of small and lightweight measurement transponders and a number of fixed base stations, is introduced. The system is operating in the 5.8-GHz industrial-scientific-medical band and can handle up to 1000 measurements per second with accuracies down to a few centimeters. Mathematical evaluation is based on a mechanical equivalent circuit. Measurement results obtained with prototype boards demonstrate the feasibility of the proposed technology in a practical application at a race track.read more

Oscillations of centroid position and surface area of soccer teams in small-sided games
TL;DR: It is concluded that over the course of a whole small-sided game, the forward-backward motion of the centroids is most strongly linearly related and therefore surface area and particularly centroid position may provide a sound basis for a collective variable that captures the dynamics of attacking and defending in soccer at team level.
