1. A method for continuously tracking location of a plurality of objects during a sporting activity, comprising:
- determining, within a tracking apparatus, when continuous location tracking information for a first tracking tag associated with a first object within a predetermined area is not available for a maximum track fail period, the first object being one of the plurality of objects;
when the continuous location tracking information for the first tracking tag is not available;
identifying a second tracking tag associated with a second object of the plurality of objects that is proximate to a last determined location of the first tracking tag, the second object having a highest probability of close proximity based on predetermined scenarios of the sporting activity;
associating the first object with the second object; and
tracking the first object by substituting a location of the first tracking tag with a current location of the second tracking tag until tracking information for the first tracking tag is available for a minimum re-track period.

Abstract
Systems and methods track a first object when continuous tracking information for the first object is not available. The systems and methods detect when the tracking information for the first object is not available. A last time of a last determined location of the first object is determined and a second object closest to the last determined location at the last time is determined. The location of the first object is associated with a location of the second object if tracking information for the first object is not available.

16. A method for associative tracking of a location of a first object, comprising:
-
receiving, within a tracking apparatus and in real time, continuous location tracking information from a first tag associated with the first object and a plurality of additional tags associated respectively with a plurality of additional objects within a predetermined area, the tracking apparatus being separated from the first and additional objects; updating, in real time, a current location of the first object and a current location of each of the additional objects based upon the received continuous location tracking information for each of the first object and the plurality of additional objects, respectively; determining, within the tracking apparatus, when the continuous location tracking information for the first object within the predetermined area is not available for a maximum track fail period; and when the continuous location tracking information for the first object is not available; determining a distance between the first object and each of the plurality of additional objects at a last time when the continuous tracking information was available for the first object and each of the plurality of additional objects; selecting a closest of the plurality of additional objects to the first object based upon the distances; and tracking the first object by substituting the location of the first object with the current location of the selected closest additional object until tracking information for the first object is available for a minimum re-track period.
