An Introduction To Understanding Ball Launch & Club Data (P1)
Introduction to Ball Launch Data
Foresight Sports’ GC2 Smart Camera System uses highspeed, high-resolution cameras to capture ball launch
conditions with a high degree of accuracy.
This portion of the reference guide provides a basic description of the conditions that are both measured (ball launch data) by the GC2 and the calculated (ball flght data) by algorithm, as well as describe how these conditions impact ball flght performance.
Introduction to Launch Condition
The launch condition is described by a combination of the following measured ball launch parameters
- Ball Speed
- Total Spin
- Launch Angle
- Spin Tilt Axis
The combination of these measured launch characteristics will determine the ball trajectory, peak height, decent angle, carry and total distance.
The following pages will describe each of these measured ball launch parameters and calculated ball flght parameters
The measurement of the golf balls velocity measured just after impact. Ball speed is the main component in generating distance.
The initial vertical angle of ascent relative to the ground plane measured in degrees. The launch angle, combined with ball spin and speed, will determine the ball carry and total distance.
(Also known as side angle or deviation angle) The initial horizontal angle relative to the target line. The azimuth, combined with side spin, will determine the fial ball position down range relative to the target-line.
A component of total spin that defies ball curvature or shot shape. Also related to the spin-tilt axis.
A component of total spin that defies ball lift and trajectory.
The total amount of spin around the tilt axis that creates curvature and lift.
The Spin-Tilt Axis is the axis that the golf ball rotates around to create shot curvature and lift.
When the spin-tilt axis is oriented to the left (looking down range), the ball’s trajectory will move from right to left. (See example 1)
When the spin-tilt axis is oriented to the right (looking down range), the ball’s trajectory will move from left to right. (See example 2)
SPIN-TILT AXIS (example 1)
SPIN-TILT AXIS (example 2)
The apex of the trajectory measured from the ground plane.
The end position distance right or left measured from the target-line.
The total distance of flght produced by initial launch condition.
The combined ball flght with bounce and roll.
