Abstract: A method and system for accurately determining player position and movements, as well as movement of other objects during a sporting event. Transmissions from a transmitter attached to the moving object are used in conjunction with a plurality of receivers and a processor to precisely determine the object's location and movement. The produced location and movement data is usable to simulate play of the game, to determine play events or outcomes, and to allow modeling and other use of the data produced. In another variation, a camera, microphone, or other directional recorder is used with the location and movement data to track play. In an additional variation, data associated with the player or other moving object is used for such purposes to assist in identification of players and to ease broadcast commentary.
