Carry distance refers to how far a batted ball travels through the air before it lands. Systems like Trackman calculate this value using high-precision Doppler radar that tracks the baseball immediately after contact and throughout its flight.

When the ball is hit, Trackman captures key parameters such as exit velocity, launch angle, spin rate, and spin axis. Using these measurements, the system builds a mathematical model of the ball’s trajectory. The radar follows the ball as long as possible, then physics-based trajectory modeling is applied to estimate the full flight path and determine where the ball would land. The distance from the point of contact to the landing point is recorded as the carry distance. 

Key Factors That Influence Carry Distance

• Exit Velocity 
  • The speed of the ball off the bat is the most important factor. Higher exit velocity generally results in greater carry.
• Launch Angle 
  • The vertical angle at which the ball leaves the bat effects how long it stays in the air. Optimal launch angles typically produce the longest carry.
• Spin Rate and Spin Axis 
  • Backspin can help the ball stay airborne longer due to aerodynamic lift, increasing potential carry.
• Environmental Conditions 
  • Weather conditions such as wind, temperature, humidity, and air density influence how far the ball travels.
• Ballpark and Altitude 
  • Higher altitudes and thinner air reduce drag, allowing the ball to travel farther.

By combining radar measurements with aerodynamic modeling, Trackman can provide highly accurate carry distance estimates, helping players and coaches better evaluate hitting performance and ball flight characteristics.
