Method of measuring a time in a sports competition using a transponder module, and transponder module for implementing the method

A method of measuring time of a competitor in a sports competition via a transponder module personal to the competitor and accompanying the competitor during the competition in a measuring system, the method comprising:

• receiving a low frequency signal transmitted from a transmission antenna of the measuring system;
• transmitting at least one signal strength of the received low frequency signal to the measuring system;
• detecting variation in motion of the transponder module via a motion sensor integrated in the transponder module;
• transmitting, via the transponder module, data indicating the variation in motion detected by the motion sensor to the measuring system;
• determining, by the measuring system, that the data indicating the variation in motion detected by the motion sensor corresponds to motion of the competitor caused by disposition of the competitor at a predetermined position in the sports competition;
• and
• determining, by the measuring system, a time of the competitor in the sports competition based on the at least one signal strength of the low frequency signal and a time of the motion of the competitor detected by the motion sensor caused by disposition of the competitor at the predetermined position in the sports competition,
• wherein the predetermined position in the sports competition comprises an intermediate position or a finish line of the competition route.
