Field: Measurement (Instruments)
Classification: CPC A  G | IPC A

Claim 6:
7. Apparatus comprising a non-volatile machine-readable medium storing a program having instructions which when executed by a processor will cause the processor to:
communicate with a plurality of anchors placed within a facility, the anchors in fixed positions following a calibration procedure reliant upon ultrawide band communications and with a plurality of movable tags, attached to individuals and/or objects used to play a sport within the facility; and
using the plurality of anchors, in two-way-ranging communication with the plurality of movable tags, to track movement of the plurality of movable tags within the facility;
communicate with a plurality of calibration tags, placed at predetermined positions relative to a space having parameters of known dimensions within the facility;
use the predetermined positions of the plurality of calibration tags to determine a placement of each of the plurality of anchors; and
store the placement of each of the plurality of anchors, thereby completing the calibration procedure, to enable tracking movement of a subsequent set of movable tags within the facility,
wherein the instructions further cause the processor to perform a recalibration procedure comprising:
using the predetermined positions of the plurality of calibration tags to determine an updated placement of each of the plurality of anchors; and
storing the updated placement of each of the plurality of anchors, thereby completing the recalibration procedure, to enable tracking movement of the subsequent set of movable tags within the facility.
