Abstract
A system and method for continuously tracking a competitor on an athletics track, including: a wireless transmitter operable to wirelessly submit a query provided with a timestamp, a wearable transponder attachable to the competitor, and configured to receive the query, to generate a transponder specific response and to wirelessly transmit the response, stationary receivers distributed across or around the athletics track. Each of the stationary receivers is configured to receive the transponder specific response and to determine a runtime, which is indicative of a point in time relative to the timestamp at which the transponder specific response has been received by the respective stationary receiver. A processor is connected to the stationary receivers and is configured to determine a position of the wearable transponder relative to the athletics track or relative to the stationary receivers on the basis of the runtimes received from the stationary receivers.
