Abstract: This document presents a system and method for installing a free-floating sensor mechanism within a ball and collecting sensor measurements from the ball during sports activity. The ball is one portion of the system, which includes sensors associated with the field, the goal or scoring portion of the field, and sensors within a wearable unit associated with players on the field. The data measurements from all sensors and the identification of the origin of the sensor measurements provide the smart sport system with the capability of providing metrics and analysis of the ball movement, player movement, and drill activities to permit players and coaches to improve and optimize player and team action on the field of play.
