GLT(Goal-Line Technology)- The most accurate way to make a decision regarding whether football crosses the goal post or not.
Can you go back to a time when the stakes were high in a match between two teams and the stadium was packed to capacity? Everyone has gathered to watch as one of their teammates attempts to send a football through the goal line.
A goal is awarded to the opposing team when the striker suddenly kicks the ball so close to the goal post that it almost crosses the line but stops short. Considers the potential adverse effects of the referee on the football team and its fans. The game’s legitimacy is harmed by this kind of human error.
Stuart Attwell, a referee in the 2008 Champions League, is notorious for having given a goal when the ball did not cross the goal line inside the goalpost.
Following such events, the football association began employing technology to provide a more precise conclusion in such cases.
- The Evolution of the Goal Line
- This innovation in cricket technology was created by Professor Paul Hawkins in 1999.
- This innovation was sanctioned by the International Federation of Association Football (IFAB) in 2006.
- Goal-line technology provided by Hawk-Eye was utilized for the first time in the Premier League that year (2006).
- Goal-line technology was first explored by FIFA in 2010.
- FIFA conducted a nine-month test in 2012 in the countries of England, Italy, Germany, and Hungary.
- Regular use of this technology was permitted by FIFA in 2013.

The principle of electromagnetic induction forms the basis of Goal-line technology. Compared to hawk-eye goal-line technology, this one is more expensive, but it’s also more reliable. An electric circuit is embedded in the ball, and a magnetic field is generated by an electric current at the goal line’s pole.
A radio signal is delivered to the system whenever the ball crosses the pole of the goal post, which causes a disruption in the magnetic field. All referees are equipped with wristwatches that receive the same signal and aid in making fair calls.

Hawk-Eye
During the 2013–14 Premier League season, this technology was introduced for the first time. Using the physics concept of Triangulation, we set up a network of high-speed cameras to monitor the location of a football. Initially developed for use in cricket’s LBW appeals, this technology has since found its way into tennis. When the ball crosses the goal line, a photo is taken and the information is sent to the referee via radio.
