Holy chunk ! Did you determine the Home Run derby the other night ? I did n’t . But if I had , I would have wonder : How did they manage to show those coolheaded balls ’ trails in real meter ?

To get the data need for the calculation , ESPN uses a 2000Hz Doppler radiolocation which follow the egg ’s speed , position and spin , given accurate data of distance trip , something that before took seconds or even mo to calculate . After calculation , the path is shown overlaid on screen in real time , chasing the ball precisely .
