Claim:
1. A method for tracking multiple movable objects, comprising: outputting electromagnetic signals from the multiple movable objects at a live sporting event; sensing the electromagnetic signals from multiple movable objects; and calculating locations of the multiple movable objects based on the sensed electromagnetic signals from the multiple movable objects; automatically choosing a first subset of the multiple movable objects to track at a first frequency; and automatically choosing a second subset of the multiple movable objects to track at a second frequency, the outputting and sensing are performed for the first subset of the multiple movable objects at the first frequency while the outputting and sensing are performed for the second subset of the multiple movable objects at the second frequency in response to the automatically choosing the first subset and the automatically choosing the second subset.
