2A2-A02 Precise measurement of the sprinter's pitch and stride using GPS carrier phase positioning measurement system(Sense, Motion and Measurement(2))

Abstract

This paper proposes a measuring device that uses carrier phase positioning GPS and an accelerometer for pitch and stride measurement of sprinters. In this system, synchronization between GPS data and step timing is used to measure pitch and stride. In this paper, improvement of the measurement system, and the method for detecting step timing by measuring the acceleration of the lumbar is discussed. Results of sprinters pitch and stride measurement by using improved measurement system are presented.
