GOLF SHOT TRACKING SYSTEM
A golf tracking system including a tag coupled to a golf club. The tag includes a plurality of sensors, each which output a signal based on a detected movement of the golf club, a microcontroller that compares each of the plurality of sensor outputs to stored reference sensor output values, and a transceiver that transmits data corresponding to the sensor outputs to a device remote from the tag based on the comparison performed by the microcontroller. The location-aware device then processes the information received from the tag to determine whether a shot should be registered.
