GoalRef

from Wikipedia, the free encyclopedia

GoalRef is a magnetic field-based goal decision system, which can be used to resolve contentious goal situations. It was developed by Fraunhofer IIS and the Danish manufacturer Select and has been a goal-line technology licensed by FIFA since 2012 .

function

Three light coils are integrated into the football, which induce a magnetic field as soon as they get into the weak electromagnetic field in the goal. The interaction between the goal magnetic field and the football magnetic field is detected by the coils behind the crossbar. The antenna data are passed on to the evaluation unit. The clear decision is then made in a fraction of a second in the small processing unit. If it is a goal, the referee receives the message "Goal" and a vibration on his wristwatch via encrypted radio technology.

history

Fraunhofer IIS has been developing sports technologies since 2003. In 2008 GoalRef was used at the Women's Junior World Cup in Macedonia. From 2010 onwards, GoalRef was adapted to football. In 2011, the first FIFA test phase was carried out. Only two technologies could do this. GoalRef has also been tested in the Danish Super League . In 2012, the tests went into the second round, with several thousand shots on goal, GoalRef managed to meet the requirements. The system was also at the Games of the Club World Cup in 2012 in the International Stadium Yokohama used by Yokohama. It was then successfully tested at the Copa Amsterdam in 2013. A combination of GoalRef and GoalControl technology was used in the 2013 FIFA Confederations Cup .

Areas of application

The system can also be used in other ball sports such as handball . Weather and visibility conditions do not affect the system due to the radio function. The data is transmitted from the evaluation unit to the referee by means of encrypted transmission. The coils in the ball allow him to distinguish the ball from similar objects, which cameras would interpret as a ball, for example. The goalkeeper can also lie completely on the ball or the player can stand in the goal without affecting the system.
