LAUSANNE: German company GoalControl became the fourth supplier of goal-line technology (GLT) to receive its FIFA licence, world football’s governing body announced yesterday.

The GoalControl system utilises 14 high-speed cameras installed around the pitch that continually track the position of the ball in three dimensions -- using X, Y and Z co-ordinates -- once it nears the goal-line.

Once the ball crosses the goal-line, an encrypted signal is then sent to the referee’s watch. 

FIFA has put the system out to tender and lannounced that two providers -- Britain’s Hawk-Eye and GoalRef of Germany -- had already been licensed. AFP
