The Three Essential Components of a Golf Simulator
Before diving into how golf simulators work, let's identify the three core components that every system needs:
1. Launch Monitor (The Brain)
The launch monitor is the heart of your golf simulator. This device captures data about your swing and ball flight, measuring everything from club speed to spin rate. Launch monitors use one of three technologies:
- Radar-based (FlightScope, TrackMan) – Uses Doppler radar to track the ball from launch to landing
- Camera-based (Ernest Sports, Foresight) – High-speed cameras capture club and ball at impact
- Infrared/Photometric (SkyTrak, Garmin) – Light sensors measure ball characteristics immediately after impact
2. Projection System (The Display)
A golf simulator projector displays the virtual course and shows your ball flight in real-time. These aren't regular home theater projectors—they're specifically designed with:
- Short throw distances to fit in compact spaces
- High brightness (3000-6000 lumens) for visibility
- Low input lag for instant ball flight response

3. Impact Screen (The Target)
The impact screen is where you hit the ball. Quality screens absorb ball impact without bouncing back, protect your projector, and provide a smooth surface for projected images. Most are made from durable materials that can handle thousands of shots.

How Golf Simulator Technology Captures Your Shot
Now let's get into the technical details of how golf simulators actually work.
Step 1: You Hit the Ball
When you take your swing and strike the ball, everything happens in milliseconds. The moment of impact is when all the magic begins—your club transfers energy to the ball, creating spin, speed, and launch angle.
Step 2: Launch Monitor Captures Data
Depending on the technology, here's what happens:
Radar-Based Launch Monitors emit radio waves that bounce off the ball and club. As the ball moves, the Doppler effect creates frequency shifts that the system translates into precise measurements. These units track the ball throughout its entire flight path, measuring:
- Ball speed
- Club speed
- Launch angle
- Spin rate (backspin and sidespin)
- Carry distance
- Total distance
- Club path
- Face angle
Camera-Based Systems use high-speed cameras (often 2-4 cameras) running at thousands of frames per second. They capture multiple images during the milliseconds before and after impact, analyzing:
- Club position and angle
- Ball position at impact
- Ball compression and deformation
- Spin characteristics from ball markings
- Club path and face angle
Infrared Systems detect when the ball passes through sensor arrays, using the interruption timing and patterns to calculate speed, launch angle, and basic spin data.
Step 3: Data Transmitted to Software
Once captured, the launch monitor sends data wirelessly (usually via WiFi or Bluetooth) to the simulator software running on a computer, tablet, or gaming console. This transmission happens almost instantaneously—typically within 20-50 milliseconds.
Step 4: Software Calculates Ball Flight
Here's where golf simulator software does the heavy lifting. Using physics engines and algorithms, the software takes your shot data and calculates:
- Ball trajectory – The path your ball will travel through the air
- Wind effects – If you've enabled weather conditions
- Landing spot – Where the ball will come to rest
- Roll out – How far the ball travels after landing based on terrain
Advanced software like E6 Connect, GSPro, and TruGolf uses real-world physics to ensure ball flight matches what would happen outdoors. The software accounts for factors like elevation changes, ball spin interaction with the ground, and even grass conditions.
Step 5: Visual Display in Real-Time
The projected image updates instantly, showing your ball flight across the virtual course. You'll see:
- Your ball leaving the tee or fairway
- The flight path with realistic arc and curve
- Landing impact and ball roll
- Updated lie and distance to the hole
The entire process—from impact to seeing your ball land on screen—takes less than a second. This real-time feedback creates an immersive experience that feels remarkably close to playing actual golf.

FAQs:
How does a golf simulator actually work?
A golf simulator works by using a launch monitor to capture data when you hit the ball—measuring speed, spin, and launch angle. That data is instantly sent to software that calculates ball flight using physics engines, then displays your shot on a projected golf course. The whole process takes less than a second from impact to seeing your ball land on screen.
What technology does a golf simulator use?
Golf simulators use three main technologies: launch monitors (radar, camera, or infrared sensors), projection systems (short throw projectors designed for low lag), and simulation software (physics engines that render courses and calculate ball flight). The launch monitor is the brain that captures all your shot data.
Do golf simulators really help improve your game?
Absolutely. Golf simulators provide objective data you can't see with your eyes—spin rate, club path, face angle, and more. This is the same technology PGA Tour pros use for practice and club fitting. You get instant feedback on every shot without weather limitations, making practice more efficient than the driving range.
How accurate are golf simulators compared to real golf?
Professional systems like the FlightScope X3C and Ernest Sports ES Tour Plus 2.0 are accurate within 1-2% for ball speed and 1-2 yards for carry distance. Mid-range units like the FlightScope Mevo Plus offer 2-3% accuracy. That's often more reliable than outdoor practice where wind, temperature, and elevation affect results. Premium simulators match or exceed outdoor accuracy.
Can you use a golf simulator in a small room?
Yes! Many golf simulators work in spaces as small as 10 feet deep, 10 feet wide, and 9 feet high. Overhead camera systems like the Ernest Sports ES Eagle Sim and VTrack need less space than radar units. The FlightScope Mevo Plus needs about 10-15 feet of ball flight, while overhead systems can work in tighter spaces. Just make sure you have swing clearance.
What's the difference between radar and camera launch monitors?
Radar launch monitors like FlightScope use Doppler radar to track the ball throughout its entire flight—great for indoor and outdoor use. Camera systems like Ernest Sports use high-speed cameras to capture impact in milliseconds—extremely accurate for club data but need controlled lighting and work best indoors. Radar needs more space; cameras need less depth but better lighting.
How much space do you really need for a golf simulator?
Most home golf simulators need 10-16 feet deep, 10-12 feet wide, and at least 8.5-9 feet tall. Radar-based systems need the longer depth for ball flight tracking (12-15 feet). Overhead camera systems can work in 8-10 feet deep. The width needs to accommodate your stance and swing, while height needs clearance for a full driver swing plus a few inches.
What's the most important component in a golf simulator?
The launch monitor is the most critical component—it's what captures your actual shot data. Without accurate ball and club tracking, the rest doesn't matter. A great launch monitor with a basic projector will give you valuable practice data. But a cheap launch monitor with expensive projection won't help your game. Start with the best launch monitor you can afford.
Do you need a subscription for golf simulator software?
It depends on the system. Most golf simulator software requires subscriptions for full course access. E6 Connect costs around $500-800/year, GSPro around $250-350/year. Some launch monitors like the FlightScope Mevo Plus include basic free software, but premium simulator experiences require paid subscriptions. Factor this into your total cost when planning your setup.
Can golf simulators work outdoors?
Radar-based launch monitors like FlightScope Mevo Plus, Mevo Gen 2, and GolfIn IDRA II work perfectly outdoors—they actually excel in open spaces. Camera-based overhead systems like Ernest Sports and VTrack are designed for indoor use only since they need controlled lighting. If you want both indoor simulator and outdoor range use, choose a radar-based portable launch monitor.
How long does it take to set up a golf simulator?
A basic portable setup with a FlightScope Mevo Plus, hitting mat, and net can be ready in 30 minutes. A permanent installation with an overhead launch monitor, mounted projector, and impact screen takes 4-8 hours for DIY or 1-2 days for professional installation. The launch monitor calibration and software setup adds another 30-60 minutes regardless of system type.
Are golf simulators worth the money?
For serious golfers, absolutely. Golf simulators let you practice year-round regardless of weather, get instant data feedback that accelerates improvement, and play world-famous courses from home. A mid-range setup ($5,000-10,000) pays for itself compared to range fees, course fees, and travel costs over 2-3 years. Plus the convenience means you'll actually practice more consistently.
What's the cheapest way to build a golf simulator?
Start with an entry-level launch monitor ($500-800), use a portable net or sheet ($100-300), and a basic projector you may already own or a budget model ($300-500). Use free software or low-cost options. Total investment: $1,000-1,500. You can upgrade components over time. The RSG Mobile or Garmin R10 are good starter launch monitors that work with affordable setups.
Do professional golfers use simulators?
Yes, extensively. PGA Tour pros use systems like TrackMan and FlightScope X3C for practice, club fitting, and game preparation. Many have home simulators for year-round training. The same technology we sell—FlightScope X3C and Ernest Sports ES Tour Plus 2.0—is used by tour professionals and top instructors worldwide for the most accurate swing and ball flight data available.
Can you play real golf courses on a simulator?
Yes! Modern golf simulator software includes dozens to hundreds of real courses. E6 Connect has over 100 famous courses like Pebble Beach and St. Andrews, GSPro adds more monthly, and TGC 2019 has thousands of community-created courses. These aren't cartoon versions—they're laser-mapped for accurate topography and beautifully rendered to look like the real thing.
