A method for determining a shot trajectory of a trackable golf ball is disclosed, wherein substantially real-time position information transmitted by the ball for a time period is received and processed to determine a shot trajectory for a golf shot, wherein a velocity value and an acceleration value is determined, and wherein an initial and final location of the shot trajectory is determined based on at least one of the acceleration and velocity values. Also disclosed is a method for determining a spin rate of a trackable golf ball, wherein the shot trajectory and a profile of the shot trajectory are determined, wherein at least one of an initial velocity, a maximum height, an initial shot angle, a curvature of the trajectory, and an in-air shot distance are calculated using the shot trajectory, and wherein the spin rate is determined based on the calculated values. |
