Golf fans have long relied on cameramen to track the golf ball in flight when watching PGA Tour events on television. However, new technologies have emerged in recent years that have dramatically changed the viewing experience. One such technology is golf flight tracking software, which has also been adopted by golfers looking to improve their game. Shot Tracer, for example, offers an array of B2B solutions and industry-leading technologies, such as its ball flight tracking solution for live TV broadcasting. Another example is Protracer, which uses strategically placed cameras to track the shot and send the data back to the sensors, which then convert it into an on-screen graphic.

What You'll Learn
Cameras and sensors
The system uses light waves created by the golf ball to track its flight and display it on a screen. A certain level of lighting is required for the system to work. The software can track multiple balls simultaneously and assign them to the correct bay. It does this by breaking the range down into triangles, like an invisible grid, and tracing the ball back to each bay, knowing the angle at which the ball enters and exits each triangle.
Protracer, created by Swedish entrepreneur Daniel Forsgren, uses a custom-built CMOS (complementary metal-oxide semiconductor) sensor to detect and track the golf ball through its entire flight path. This flight-tracking capability is then converted into a graphic that can be displayed on TV in real-time. The camera used to capture the shot is usually fixed behind the golfer as they hit.
Toptracer, which was Protracer's name before it was purchased by Topgolf in 2016, uses metal oxide semiconductors. These transistors were invented in the 1950s and are still produced today in their trillions. They are used in everyday technology such as phones and TVs and form a significant part of the Toptracer range.
Shot Tracer offers state-of-the-art consumer software applications and B2B solutions. Their award-winning Smart Tee and ball flight tracking solutions are used in live TV broadcasting. Shot Tracer AR is an augmented reality golf app that creates impressive augmented reality tracers based on a pre-set flight path simulation. Shot Tracer Live is a real-time ball flight-tracking solution that can live stream to multiple streaming platforms.

Metal oxide semiconductors
Golf ball-tracking technology, such as Toptracer and Protracer, uses metal oxide semiconductors to track the flight of a golf ball and display it on a screen or television in real time. Metal oxide semiconductors are transistors that were invented in the 1950s and are still produced today. They are used in everyday technology such as phones and TVs.
The traditional metal-oxide (SiO2)-semiconductor (Si) structure is created by growing a layer of silicon dioxide (SiO2) on top of a silicon substrate. This is typically done through thermal oxidation, followed by the deposition of a metal or polycrystalline silicon layer. Silicon dioxide is a dielectric material, so its structure is equivalent to a planar capacitor, with one of the electrodes replaced by a semiconductor.
The MOS structure can be visualized as a sandwich, with a thin layer of silicon oxides in the middle, between a metal layer and a semiconductor (Si) layer. The metallic gate should be thick enough to be an equipotential region, where every point has the same potential in space. The oxide layer in the middle should be a perfect insulator with zero current flowing through it under all static biasing conditions. The semiconductor layer should be uniformly doped with donors or acceptors as p-type or n-type semiconductors.
The interaction between the metal and oxide orbitals in MOS results in a significant disparity in charge carrier transport. Metal oxide semiconductors have a high degree of ionic bonding, with their conduction band minimum (CBM) and valence band maximum (VBM) consisting mainly of the metal (M) ns and oxygen (O) 2p orbitals, respectively. The smaller electron effective mass in metal oxides indicates better electron transport compared to hole transport.

Shot Tracer app
Golf flight trackers use cameras and sensors to create a 3D space where objects entering that space are tracked. The light waves created by the golf ball allow the software to track its flight and show it on a screen. This technology is used in TV broadcasts for top tournaments.
The Shot Tracer app is a ball flight tracking app for smartphones that is used by golf professionals and amateurs alike. It is available for iOS, Android, PC, and macOS, and has been voted the Best Golf App by Golf Digest and Golf Magazine. The app offers ball flight tracking, swing and putt tracing, 3D map overlays, and more. It also has a standalone PC program for working with video captured in various ways.
The Shot Tracer app is designed to help users create engaging golf videos and drive their businesses forward. It offers an array of business solutions to help individuals and organisations create new revenue streams in the golf business. The app provides real-time ball flight tracking with live streaming capabilities to multiple streaming platforms. It also allows users to trace their swing and putt, measure drive distance, and add 3D maps to their golf videos.
The Shot Tracer app has received mixed reviews. Some users have praised it for its ability to elevate their game and create impressive social media posts. They have also found it useful for video editing, as it does the bulk of the work automatically. However, other users have criticised the app for being difficult to use, with manual editing features that don't work properly and issues with uploading videos.

Real-time analytics
Golf flight trackers have revolutionised the viewing experience for fans of televised golf tournaments. One of the most popular software used for this purpose is Protracer, which was developed by Swedish entrepreneur Daniel Forsgren and later rebranded as Toptracer when it was purchased by Topgolf. Protracer uses a custom-built CMOS (complementary)
Toptracer's technology works similarly to Hawk-Eye, which is used in tennis. Strategically placed cameras track the ball and send data back to the sensors, which is then converted into an on-screen graphic. This technology has also been leveraged to provide real-time shot analytics, such as ball speed, apex, curve, and carry. Shot Tracer, another ball flight tracking solution, offers similar capabilities and is used by industry-leading companies like the Golf Channel and the PGA Tour.
The ability to track shots and provide instant feedback has significantly enhanced the experience of playing and watching golf. Real-time analytics have made it possible to visualise ball flight paths, understand the mechanics of each shot, and appreciate the incredible distances that professional golfers can achieve. This technology has also opened up new revenue streams for the golf industry, with companies creating engaging content and providing golfers with tools to improve their game.
