Topgolf uses radar and computer vision to track every shot you hit

Topgolf's tracking system combines radar technology and high-speed cameras to measure where your ball goes, how fast it travels, and how it spins. The system doesn't use GPS or embedded chips in the balls — instead, it watches the ball in flight and calculates its path in real time. This is why you can use any golf ball at Topgolf, and why the system works indoors under a roof.

The radar sits in the bay ceiling and sends out radio waves that bounce off the moving ball. A computer processes the radar return to calculate the ball's speed, launch angle, and direction. At the same time, high-speed cameras mounted around the bay capture video of the ball's flight and landing, which the system uses to verify the radar data and pinpoint exactly where the ball landed on the grass or in a target zone.

All of this happens in milliseconds. By the time your ball lands, Topgolf has already recorded your shot data and updated your score on the screen in front of you.

Key Takeaways

  • Topgolf uses radar to measure ball speed, launch angle, and direction as the ball leaves the club.
  • High-speed cameras verify the radar data and track where the ball lands on the range.
  • The system works with any golf ball because it tracks the ball in flight, not an embedded chip.
  • All measurements happen in real time, so your score updates instantly after each shot.
  • The radar and cameras are mounted in the bay ceiling and work whether you're indoors or outdoors.

How the radar measures your shot

The radar transmitter in the ceiling sends out a continuous radio signal. When your golf ball moves through that signal, the radio waves bounce off it and return to a receiver. The system measures how the returning signal has changed — a principle called the Doppler effect — to calculate how fast the ball is moving and in what direction.

From the radar data alone, Topgolf can determine ball speed, launch angle (the angle the ball leaves the club face), and horizontal direction. The radar is accurate enough to distinguish between a shot that goes straight and one that curves left or right, and it can measure spin rate by analyzing how the radio waves bounce off the rotating ball.

Radar works through rain, fog, and darkness because radio waves pass through those conditions. This is why Topgolf's outdoor bays function in weather that would shut down a traditional driving range, and why the indoor bays don't need windows or natural light to track accurately.

How the cameras confirm and refine the data

While the radar is measuring the ball in flight, high-speed cameras mounted around the bay are recording video at hundreds of frames per second. These cameras serve two purposes: they verify that the radar reading makes sense, and they track exactly where the ball lands.

The radar can tell you the ball's trajectory, but it's less precise about the final landing spot — especially if the ball bounces or rolls. The cameras see the ball hit the ground and can pinpoint its resting position to within a few inches. The system combines the radar's flight data with the camera's landing data to give you an accurate picture of the full shot.

If the radar and cameras disagree significantly, the system flags the shot for review. This is rare, but it's a built-in check to catch measurement errors before they affect your score.

Why Topgolf doesn't use GPS or chip-embedded balls

GPS works outdoors by receiving signals from satellites, but it's not accurate enough for golf — a GPS reading can be off by 10 to 30 feet, which is too much error for a sport where precision matters. GPS also doesn't work indoors at all, which would make Topgolf's indoor bays impossible.

Embedding a tracking chip in every ball would require Topgolf to manufacture or modify millions of balls, and players could accidentally take them home or lose them. Radar and camera tracking avoids this problem entirely: the system works with any standard golf ball, and players can bring their own ball or use Topgolf's.

Radar and camera systems are also faster. They measure the shot while the ball is still in the air, so your score updates before the ball lands. A chip-based system would have to wait for the ball to come to rest and be read by a receiver on the ground.

What data Topgolf actually records

Topgolf's system records the following measurements for each shot: ball speed, launch angle, spin rate, horizontal direction, carry distance (how far the ball flies through the air), and total distance (carry plus roll). It also records where on the club face you made contact — whether you hit the center, the toe, or the heel — by analyzing the ball's initial acceleration.

This data is stored on Topgolf's servers and linked to your account if you use a membership card or app. You can review your shot history, see trends in your swing, and compare your performance across different visits. Topgolf uses this data to power its games and scoring systems, and to generate the statistics you see on the screen during play.

The system does not record video of you or audio from the bay. The cameras are pointed at the ball and the landing area, not at the golfer.

How accuracy compares to professional golf equipment

Professional golf uses launch monitors like TrackMan and FlightScope, which work on the same radar and camera principles as Topgolf. These systems are used on PGA Tour broadcasts and in professional coaching, and they measure the same metrics Topgolf does.

The main difference is precision and cost. A professional launch monitor can cost $20,000 to $100,000 and is calibrated to measure within a fraction of an inch. Topgolf's system is built for speed and durability across hundreds of bays, so it prioritizes consistency over extreme precision. For a casual golfer or someone learning the game, the difference is not meaningful — Topgolf's measurements are accurate enough to show you real patterns in your swing.

Topgolf publishes accuracy specifications for its system, though the exact tolerances vary by metric. Ball speed is typically accurate to within 1 to 2 miles per hour, and distance measurements are within a few yards. If you're comparing your Topgolf stats to a professional coaching session, expect small differences due to different equipment and calibration.

Why the system sometimes misses or miscounts a shot

Topgolf's radar and cameras are very reliable, but they can occasionally miss a shot or misread it. This usually happens in specific situations: if you hit a very short chip shot that barely leaves the ground, the system might not register it as a valid swing. If two players hit at exactly the same time from adjacent bays, the radar can sometimes confuse which ball belongs to which bay.

If you hit a ball that goes far outside the bay boundaries — into an adjacent bay or off the range entirely — the system may not track it because the cameras and radar are focused on the designated landing area. Topgolf's software is designed to ignore stray shots, so they won't count against your score, but you also won't see data for them.

If you believe a shot was miscounted or missed entirely, most Topgolf bays have a button to flag the issue for staff review. The staff can manually adjust your score if they determine the system made an error.

Frequently Asked Questions

Can I bring my own golf ball to Topgolf?

Yes. Topgolf's system tracks any golf ball, so you can use your own ball or use one of Topgolf's. The tracking works the same way regardless of which ball you use. Some players prefer their own ball for consistency, while others use Topgolf's to avoid wear on their personal equipment.

Does Topgolf track backspin and sidespin separately?

Topgolf measures total spin rate, which combines backspin and sidespin. The system can infer how much of each type of spin you have based on the ball's trajectory and landing position, but it doesn't display backspin and sidespin as separate numbers the way a professional launch monitor does. The games and scoring use total spin rate to calculate shot results.

How does the system work if you hit a ball that bounces back toward you?

The radar and cameras track the ball's initial flight and landing. If a ball bounces backward or rolls back toward the bay, the system has already recorded the shot based on where it first landed. The bounce doesn't affect your score or the data recorded.

Can Topgolf's system work outdoors in bright sunlight?

Yes. The radar works in any lighting condition because radio waves are not affected by sunlight. The cameras use infrared and other techniques to track the ball even in bright daylight. Topgolf's outdoor bays function in full sun, overcast conditions, and darkness.

What happens if the radar or cameras break?

If the tracking system fails, Topgolf staff will close that bay and take it out of service until it's repaired. The system is redundant — if one camera fails, the others can still track the ball — so a complete failure is rare. Most Topgolf locations have backup bays available if one goes down.
