    Goal Line Technology

    Uploaded by

    Rahul Aryan
    Goal line technology uses electronic devices to help determine when the ball has completely crossed the goal line to assist referees in making accurate calls on goals. It is needed because disallowed goals have negatively impacted important matches. There are four main types: GoalMinder uses cameras but only provides visual evidence; Cairos uses magnetic fields and sensors but only works with Adidas balls; GoalRef is similar to Cairos but can work with any ball; and Hawk-Eye uses cameras like in tennis but the ball must be mostly visible. Both GoalRef and Hawk-Eye are considered the best options currently.

    Road Map
    What is goal line technology?
    Why is it needed?
    Famous occurrences of missed calls
    Four different types of goal line technology
    Wrap-up/Conclusion
    What is goal line technology?
    A method used to determine when the ball has
    completely crossed the goal line with the assistance of
    electronic devices and at the same time assisting the
    referee in calling a goal or not.
    Why is it needed?
    Disallowed goals have negatively impacted big games
    It would make referee’s calls easier
    It would eliminate controversial goals
    Famous Occurrences
    2000 African Cup of Nations
    Manchester United vs Tottenham in 2005
    2009 Crystal Palace vs Bristol City
    2010 World Cup: England vs Germany
    2011 FA Cup: Chelsea vs Tottenham

    Cons:
    Only compatible with Adidas balls
    GoalRef
    Founded by Peter Mikelson
    Very similar to the Cairos System
    Uses same magnetic field sensors
    Coils are added to goal frame
    Creates a “light curtain” within the net
    Sensors are placed between inner ball and leather
    GoalRef: Pros and Cons
    Pros:
    Instant verification to referee

    Cons:
    Ball has to be 25% visible
    High installation costs
    Conclusion
    Goal line tech will drastically help officials
    Eliminate missed calls that affect the game
