Abstract
A system for identifying a location of one or more assets in a predefined two-dimensional area comprises at least three tracking stations and one or more tracking tags. Each tracking station selectively emits a vertical laser line upon which is embedded a unique identifier, selectively sweeps its laser line about its central axis such that each tracking station's laser line sweeps across at least a portion of the predefined 2-D area, and selectively transmits a current angle of its laser line as its laser line sweeps about its central axis. Each tracking tag detects a laser line from at least three tracking stations within its line of sight. Each tracking tag decodes the unique tracking station identifier, receives the current angle from the tracking station corresponding to the detected laser line, and stores the decoded unique tracking station identifier and the received current angle.
