|Abstract:||The main objective of this research is to develop an optimal solution in terms of precision, cost and weight of the equipment for computing the athlete’s velocities and accelerations using high data rate GPS measurements. This thesis is divided into three major sections. First, the theory about the computation of velocity is presented. Then, the theory about the computation of acceleration is shown. Finally, results of field tests are given. These tests were conducted to compare different parameters used to define an optimal strategy to obtain precise velocities and accelerations. The principal parameters tested are: computation modes (stand-alone or differential); processing algorithms using pre-computed positions, Doppler frequencies or carrier phase measurements; weighted observation matrices using satellites elevation angles or signal/noise ratio; filtering techniques using a moving average or Fast Fourier Transform; and GPS receivers of different quality (low cost receiver or geodetic receiver).|
