![]() All three sensors collect data in three axes, or directions, allowing sensitive ‘maps’ of athlete movements and actions to be created. ![]() These inertial sensors comprise an accelerometer (to measure accelerations and force), a gyroscope (to measure rotation), and a magnetometer (to measure body orientation). This is the basis by which GPS enables us to analyse player movements during training and matches.Īlthough velocity and directional information is useful in terms of basic speed and distance calculations, Catapult GPS devices also contain a number of inertial sensors that enable practitioners to conduct more detailed levels of athlete monitoring. As timestamps are simultaneously transmitted, distance covered can be represented relative to time as speed profiles. These distances and satellite locations are used to compute the location of the receiver at a specific point in time using a process known as trilateration.Īs objects (or athletes) change position over time, their movement profiles (and thus displacement/distance covered) can be plotted by regular repetition of this process. GPS-based technologies are used throughout sport to support performance monitoring, but how do they work, what do they measure, and how do they benefit athletes and coaches ?Īt the most fundamental level, a GPS receiver calculates position by timing the signals emitted by GPS satellites orbiting the Earth.Įach satellite continually transmits messages that include the time of transmission and the satellite’s position at that time, information that the receiver uses to compute the distance to each satellite using the speed of light. #Pictures of a catapult series#Introducing you to the science behind our technology, the Catapult Fundamentals series explains sports science concepts and principles, and looks at the ways athlete monitoring systems can be used to improve team and player performance.
