Abstract
This paper proposes a measuring device that uses carrier phase positioning GPS and accelerometers for pitch and stride measurement of athletes. In this system, Synchronize the timing of the ground contact measured by accelerometer and position information measured by GPS to measure the pitch and stride. In this paper, System summary and method of detecting contact with the ground using the accelerometer. And measurement principles of carrier phase positioning GPS and experiments that evaluate the precision and accuracy of carrier phase positioning GPS. Matching of position data and ground contact data, pitch and stride measurement using this system are described.
