Abstract
A method and system provides for determining position information for tracking tags relative to a plurality of tracking stations. The method and system includes initiating a wake cycle at a first time including pausing for a first time period and thereafter emitting a blast of light in a light sweep. The method and system includes the tracking tags waking at the first time and activating a photoreceptor embedded therein. The tracking tags detecting the blast of light and initiating a tracking timer therein. From there, the method and system includes the tracking stations emitting a vertical laser in a circular rotation at a rotational speed. Whereby, the tracking tags detect the vertical laser at a timestamp and detect an angle between the tracking tag tracking stations based thereon.
