What You'll Learn
Golf simulator technology
There are a variety of ways golf simulators track your shot, with the most accurate systems using a combination of two or more technologies. Some of the most common tracking methods include:
- Photometric cameras: High-speed images are taken and analysed to determine ball and club data.
- Doppler radar: Signals emitted by the launch monitor are interrupted by the ball in flight, allowing the system to calculate various data points.
- Optical sensors: Usually placed inside a hitting surface, these sensors track the ball and club as they pass, determining data such as club path and ball speed.
- Infrared light: Systems using infrared can track data such as ball speed, launch angle, and direction.
Other equipment used in golf simulators includes something to hit off of (like a mat) and into (like an impact net or screen), a launch monitor to simulate ball flight, and a PC/phone/tablet to process the software data. For a more immersive experience, a projection screen and simulator projector can be used.
The cost of golf simulators varies widely depending on the technology used, with prices ranging from around $1000 to $50,000. Some of the top-of-the-line models can even cost upwards of $50,000. However, there are also more affordable options available, such as entry-level consumer devices that can be taken to a driving range.
While golf simulators can provide a lot of benefits, there are also some differences between simulator golf and real golf that are important to note. For example, it is difficult to simulate playing out of the rough or bunkers in virtual golf, and the 'feel' of hitting a shot may be different. Additionally, environmental conditions such as temperature, humidity, and elevation can affect the accuracy of a simulator, so it is important to set up your simulator correctly.

Environmental conditions
Golf simulators provide an extremely accurate and realistic golfing experience. They employ a variety of technologies, including photometric cameras, Doppler radar, optical sensors, and infrared light, to track and calculate ball and club data. However, their accuracy can be influenced by certain environmental conditions.
Additionally, physical surroundings can interfere with the radar fields used by simulators. Metal roofs, steel walls, and aluminum siding can disrupt the technology's ability to capture ball flight metrics, leading to potential inaccuracies.
The construction and maintenance of golf courses can have both positive and negative environmental implications. On the one hand, golf courses can support wildlife sanctuaries, protect water resources, and promote environmental conservation. On the other hand, they may contribute to deforestation, habitat loss, and the use of harmful chemicals, such as pesticides and fertilizers, which can affect nearby waterways and ecosystems.
While golf simulators may not fully replicate the 'feel' aspect of real golf, they offer a more environmentally friendly alternative to traditional golf courses. They eliminate the need for large areas of land and the extensive use of water and chemicals. By opting for golf simulators, players can still enjoy the game while reducing their environmental impact.

Radar interference
Radar-based golf launch monitors, such as Flightscope or Trackman, are widely considered to be highly accurate. They use Doppler Radar technology to emit radio/radar signals that bounce off the flying golf ball, allowing the system to measure the change in wave frequencies and calculate the ball's speed, launch angle, direction, spin, and more.
However, radar interference can impact the accuracy of these systems. Here are some factors that can cause radar interference in virtual golf:
Metal Objects and Reflective Surfaces
Metal objects and reflective surfaces within the radar field can interfere with the readings of radar-based launch monitors. Metal roofs, steel walls, aluminium siding, and metal components of golf equipment or nearby items can cause issues. It is recommended to minimise the number of metal objects in the radar viewing area to reduce interference.
Electronic Devices
Electronic devices such as air conditioners, fluorescent lights, fans, computers, televisions, and refrigerators can also cause radar interference. The Mevo+ manual, for example, mentions these devices as potential sources of interference.
Lighting Conditions
Lighting conditions can affect the performance of radar-based systems. While radar systems are generally less sensitive to lighting than camera-based systems, changes in lighting, shadows, and brightness can still impact their accuracy.
Environmental Factors
Environmental factors such as temperature, humidity, and elevation can also influence the accuracy of virtual golf simulations. These factors can affect the distance of the shot, particularly with longer clubs.
Outdoor Space
Radar launch monitors tend to perform better in outdoor spaces, as they have more room to read the ball's flight path after it has been struck. Indoors, the limited space may lead to missing readings or interference from nearby objects.
While radar-based systems provide accurate data points, it is important to be aware of potential sources of radar interference to ensure optimal performance and accuracy in virtual golf simulations.
