1. A method for determining positioning information, the method comprising:
for each of a plurality of tracking stations, initiating a wake cycle at a first time including pausing for a first time period and after the first time period emitting a blast of light in a light sweep;
in one or more tracking tags, waking at the first time and activating a photoreceptor embedded therein;
the one or more tracking tags, detecting the blast of light and initiating a tracking timer therein;
for each of the plurality of tracking stations, emitting a vertical laser in a circular rotation at a rotational speed; and
in the one or more tracking tags, for each of the plurality of tracking stations, detecting the vertical laser at a timestamp and detecting an angle between the tracking tag and each of the plurality of tracking stations based on the timestamp and tracking timer.
