John Hansman wave-GPS race car fishtail monitoring

Precision GPS application; Hansman (MIT Aero/Astro) using wave GPS to monitor tail-end movement of race cars to control brakes and prevent spin-out.

Kathleen, you were in Aero and Astro, right? You know John Hansman, Professor Hansman? Okay, you didn't know him. John was developing wave GPS — the only reason I know about this — he was looking at race cars and wanted to see when a race car might start to fishtail. He was using GPS to monitor the movement of the tail end of the car, to see if it moved one or two inches off to the side, so he could control the speed and brakes of the wheels to prevent a spin out. That's pretty precise, if you like to race.
