Goal Line Technology is used to determine whether the goal has been scored or not with the help of Electronic aid. There’s no single technology called the Goal-Line Technology or System (although, due to the substantial creativity required to develop the name, I doubt this name would’ve crossed their minds), but the technology is implemented in a few different ways. What are Mutations and what are the different types of Mutations? Again, as soon as the ball crosses the line, the antennas sense a change in their magnetic fields and relay the data to a computer, which decides whether the ball has crossed the line or not. GoalRefGoalRef uses a similar magnetic field-based technology to Cairos GLT, but instead of the ball acting as a sensor, the goal frame detects the passing of the ball. (Photo Credit : Maxxl² / Wikimedia Commons). The first goal to be called by Hawk-Eye was Dzeko's goal for Manchester City against Cardiff City on 18 January 2014.

The 2012 Club World Cup was the first tournament to implement this technology. One common method for tracking the ball is to use camera technology. Hawk eye cameras also allow for evaluating and simulating trajectories of an object if it had been allowed to continue its motion or if its motion hadn’t been interrupted by an obstacle. by Peter Shard . His alacrity is sometimes less revered and often taken for granted. Goal-line technology and how it works Ever since the dawn of football, governing bodies have been looking for ways to avoid controversial refereeing decisions.

Hawk-Eye, the first ball-tracking technology to be put into use, was developed in Romsey in Hampshire in 1999 by Dr Paul Hawkins and engineers at Siemens subsidiary Roke Manor Research Limited. This bundle of technologies relies either on physical cameras tracking the ball or a changing magnetic field. Still, he must be unprejudiced, despite the incoming spate of suggestions from a prejudiced crowd. The Goal-line technology (GLT) testing procedure is based on the requirements set by the International Football Association Board (IFAB) and aims to test the functionality and robustness of GLT systems and to determine its accuracy. The electronic circuit is composed of three copper coils in a bunch that is attached between the bladder and surface panel. Goal-line technology and how it works. Hawk-Eye was used in the 2013-2014 Premier League season in the UK. Brazil 2014 is the first FIFA World Cup in which the refs have a little technological assistance to help them know whether the ball crossed the goal line.
