How Do Golf Launch Monitors Work?

There are two main technologies used in launch monitors:

1. Camera-Based (Photometric) Launch Monitors

• Use high-speed cameras to capture images of the golf ball immediately after impact.

• Analyze spin, launch angle, and direction to predict the full ball flight.

• Best for: Indoor golf simulators with limited space.

• Popular examples: Foresight Sports GCQuad, SkyTrak+.

2. Radar-Based (Doppler) Launch Monitors

• Use Doppler radar (the same technology used in weather tracking) to follow the ball through the air.

• Track ball flight over long distances and measure club movement.

• Best for: Outdoor use or large indoor setups.

• Popular examples: TrackMan, FlightScope Mevo+.

Some premium systems even combine radar and camera technology for the most precise results possible.

Key Data Measured by Launch Monitors

A quality golf launch monitor provides dozens of stats, but here are the most important:

• Ball Speed – How fast the golf ball leaves the clubface.

• Launch Angle – The upward angle the ball takes off at.

• Spin Rate – Measures backspin and sidespin, which affect flight and curve.

• Carry Distance – How far the ball travels before it lands.

• Club Path & Face Angle – Advanced data that shows how the club was moving at impact.

This information feeds into the golf simulator software, which recreates your shot with incredible accuracy.

Why Accuracy Matters in Golf Simulators

Not all launch monitors are created equal. High-end models provide tour-level accuracy, making them ideal for players who want precise performance feedback or professional club fitting. More affordable options may estimate certain data points, which is fine for entertainment-focused simulators but less ideal for serious practice.

The Bottom Line

The golf simulator launch monitor is what makes an indoor golf setup truly work. By using either camera-based photometric systems, radar-based systems, or a combination of both, launch monitors capture every detail of your swing and ball flight.

So, the next time you tee it up indoors, you’ll know exactly how your simulator translates your swing into a lifelike round of golf. Whether you’re looking to practice more effectively or just enjoy the game year-round, understanding how golf simulators work starts with knowing how launch monitors power the experience.
