Just as the coaster was about to pull away to begin the ride, I fired up V-Cockpit GPS by Alexander Gross on my iPhone and held it firmly for the duration of the road. Space Mountain peaked at 2 G’s and bottomed out at -1 G. The chart is pretty interesting. I’ve attached the raw data for fun. I need to try this on a more vigorous ride in the future. V-Cockpit GPS tracks acceleration and speed. It allows you to export your data to CSV format via email.
