Golf Simulators Glossary

Common terms you’ll see across golf simulators coverage. 47 entries.

Angle of Attack: The vertical direction the club head is moving at impact, expressed in degrees up (positive) or down (negative). Drivers are typically struck with a slightly positive angle of attack to optimize launch conditions.
API Integration: A software connection that allows a launch monitor to send shot data directly to third-party simulator platforms. Open or published APIs allow a single launch monitor to be used with multiple software platforms.
Ball Flight Zone: The unobstructed corridor of space between the golfer's tee position and the impact screen through which the ball must travel. Any objects or people inside this zone during a shot create a safety hazard.
Ball Return: A ramp or channel system built into or placed in front of the hitting mat that rolls putted or chipped balls back to the golfer, reducing the need to retrieve shots manually.
Ball Speed: The velocity of the golf ball immediately after impact, measured in miles per hour or meters per second. Ball speed is the most direct indicator of how much energy was transferred from the club to the ball.
Calibration: The process of configuring a launch monitor or simulator software so that measured data accurately reflects real-world shot results. Proper calibration ensures the numbers you see on screen translate reliably to on-course performance.
Carry Distance: The distance the ball travels through the air from impact to first landing, before any bounce or roll. Carry distance is the most useful distance metric for club fitting and course management.
Ceiling Height: The vertical clearance from floor to ceiling in the simulator space, which must accommodate a full golf swing without the club striking overhead obstacles. A minimum of 9 feet is often cited, but taller golfers or those with steep swings may require more.
Club Head Speed: The velocity of the club head at the moment it strikes the ball, typically measured in miles per hour. Higher club head speed is the primary driver of greater potential distance.
Club Path: The direction the club head is traveling through the impact zone, measured in degrees relative to the target line. Club path and face angle together determine whether a shot draws, fades, or flies straight.
Club Sensor: A device attached to the club shaft or grip that measures swing data such as club head speed, tempo, and path. Club sensors are sometimes used as low-cost alternatives to full launch monitors.
Creative Golf 3D: A versatile golf simulator software platform that supports practice modes, game modes, and entertainment mini-games alongside realistic course play. It is frequently used in commercial simulator installations as well as home setups.
Data Delay: The lag between when a shot is struck and when the launch monitor data appears in the simulator software. Even small delays can disrupt immersion; typical acceptable delays are under 300 milliseconds.
DIY Simulator: A home simulator built by the owner from individually sourced components rather than purchased as a pre-matched set. DIY builds can offer significant cost savings but require research to ensure hardware and software compatibility.
Dynamic Loft: The effective loft of the club face at the moment of impact, accounting for shaft lean and delivery conditions. Dynamic loft differs from the club's stated loft and is a key determinant of launch angle and spin.
E6 Connect: A golf simulator software platform offering photorealistic courses and multiplayer modes, compatible with many popular launch monitors. It is commonly bundled with commercial and home simulator packages.
Enclosure: A frame-and-screen structure that surrounds the hitting area, containing errant shots and holding the impact screen in place. Enclosures range from simple net frames to fully enclosed bays with side and top panels.
Face Angle: The direction the club face is pointing at impact relative to the target line, measured in degrees open or closed. Face angle is the dominant factor in determining the initial direction of the ball flight.
GSPro: A realistic PC-based golf simulator software platform known for its accurate ball physics and large library of community-created courses. It supports a wide range of launch monitors via API connections.
Hitting Mat: A synthetic turf mat that replicates a grass lie and absorbs the impact of club strikes. Mat quality affects both feel at impact and long-term joint health for the golfer.
Home Simulator: A personal golf simulator installed in a private residence — typically in a garage, basement, or spare room — combining a launch monitor, impact screen, projector, and simulator software for year-round indoor play and practice.
Impact Screen: A durable, tightly-woven fabric screen that stops golf balls and simultaneously serves as the projection surface for simulator graphics. Screen quality affects both safety and image clarity.
Impact Screen Tension: The degree to which an impact screen is stretched or tightened within its frame. Proper tension prevents the screen from billowing excessively on impact, extends screen life, and improves image flatness and clarity.
Indoor Golf: The broad category of golf practice or play conducted inside a building, ranging from simple net-and-mat setups to fully immersive simulator bays with course-play software. Home simulators are the premium end of the indoor golf spectrum.
Launch Angle: The vertical angle at which the ball leaves the club face, measured in degrees above the ground. Optimal launch angle varies by club and swing speed and directly affects carry distance and trajectory shape.
Launch Monitor: A device that measures the ball and/or club at the moment of impact to produce data such as ball speed, spin rate, and launch angle. Launch monitors are the core sensor of any home simulator setup.
Low Point: The lowest point in the arc of the club head's swing path, ideally occurring at or just past the ball for irons and at the ball for drivers. Low point location affects strike quality and angle of attack.
Net: A barrier of mesh material used to catch golf balls, either as a standalone practice net or as side and rear containment within a simulator enclosure. Net gauge and depth determine how safely it stops full-speed shots.
Overhead Launch Monitor: A launch monitor mounted above the hitting area, pointed downward, that captures club and ball data from an elevated angle. Overhead placement can free up floor space and reduce obstruction for the golfer.
Photometric Launch Monitor: A launch monitor that uses high-speed cameras and image processing to capture the ball and club face at impact. These units can read accurately with minimal ball flight, making them well-suited for shorter indoor spaces.
Projector: A display device that throws an image from a lens onto the impact screen. For simulators, brightness (measured in lumens) and resolution are the key specs to match to your screen size and room lighting.
Putting Mat: An elongated mat with a surface designed to replicate green speed, used for practicing putting strokes indoors. Some simulator setups integrate a putting mat in front of the hitting area for on-screen putting.
Radar Launch Monitor: A launch monitor that uses Doppler radar to track the ball in flight and derive club and ball data. Radar-based units typically require several feet of ball flight to read accurately, making room size an important consideration.
Short-Throw Projector: A projector with a lens designed to produce a large image from a relatively short distance, typically a throw ratio of 0.4–1.0. Short-throw projectors are a middle-ground option between standard and ultra-short-throw models for simulator rooms.
Side Netting: Panels of netting installed on the sides of a simulator enclosure to catch balls that miss the impact screen. Side netting is a critical safety feature, especially for beginners with inconsistent strike patterns.
Sim Software License: A purchased or subscription-based authorization that unlocks a simulator software platform for use. Licensing models vary widely — some are one-time purchases, others are annual subscriptions, and some require a specific hardware pairing.
Smash Factor: The ratio of ball speed to club head speed, used as a measure of impact efficiency. A smash factor of 1.50 with a driver means the ball left the face at 1.5 times the speed of the club head.
Spin Axis: The tilt of the ball's spin axis relative to horizontal, measured in degrees. A tilted spin axis causes the ball to curve left or right in the air — this is the true cause of draw and fade ball flight.
Spin Rate: The total revolutions per minute the ball is spinning after impact. Spin rate interacts with launch angle to determine trajectory, carry distance, and how the ball behaves when it lands.
Stance Pad: A thin, cushioned mat placed alongside the hitting mat where the golfer stands during a shot. It provides comfort underfoot and can help level the stance when the hitting mat has a raised surface.
Swing Plane: The geometric plane or angle on which the club travels during the backswing and downswing. Instructors use swing plane data to diagnose over-the-top, flat, or on-plane swing patterns.
Swing Plane Clearance: The amount of unobstructed space above and around the golfer sufficient to complete a full swing without hitting walls, beams, or the projector. Inadequate clearance is one of the most common room-planning oversights.
Tee Insert: A rubber or foam fitting recessed into the hitting mat that holds a golf tee at a consistent height. Replaceable inserts prevent the mat from wearing out prematurely from repeated driver strikes.
Throw Distance: The distance from the projector lens to the impact screen, which determines what image size the projector can produce. Always check your projector's throw ratio against your available depth before purchasing.
Total Distance: The full distance from impact to where the ball comes to rest, including carry, bounce, and roll. Simulator software uses carry distance and estimated roll algorithms to compute total distance.
Turnkey Package: A complete, pre-matched simulator bundle sold by a retailer or manufacturer that includes all necessary hardware and software components. Turnkey packages simplify purchasing but typically cost more than equivalent DIY builds.
Ultra-Short-Throw Projector: A UST (Ultra-Short-Throw) projector can produce a large image from only a few inches or feet away from the screen, making it ideal for simulator enclosures where throw distance is limited.
