Goal Line Technology Planned For World Cup 2014

Via Soccerex = Goal-line technology (GLT) will be used at this year’s Confederations Cup and the 2014 World Cup after FIFA on Tuesday launched a tender process for proposals from companies interested in fulfilling the contract for its showpiece competitions.

Tuesday’s announcement comes after the International Football Association Board (IFAB) in July gave the green light to the introduction of GLT by approving the Hawk-Eye and GoalRef systems, which were subsequently given their most high-profile tests to date at the 2012 Club World Cup venues in Toyota and Yokohama. FIFA said the systems were “successfully” implemented at December’s tournament, but added an additional two companies are close to joining Hawk-Eye and GoalRef in securing FIFA licences. A third system, developed in Germany, has already passed the necessary tests with the providers in licensing discussions, while another German system has also been tested with the results due this week.

The two currently approved systems work using completely different technology. GoalRef creates the radio equivalent of a light curtain. Low magnetic fields are produced around the goal, and as soon as the ball, which is fitted with a compact electronic device, fully crosses the line, a minor change in the magnetic field is detected, thus allowing the exact position of the ball to be established. Hawk-Eye uses six to eight high-speed cameras set up at different angles at each end of the pitch to calculate the exact position of the ball. The data from the cameras is then transferred to video software creating a 3D graphic image of the ball’s trajectory.
