Abstract

See full text

Methods and systems for location detection are disclosed. One method includes a plurality of base stations of a location system obtaining information about at least one tag associated with the location system. One of the plurality of base stations is designated as a master base station for each tag. Each master base station electro-magnetically transmits beacons to each tag that the master base station has been designated as the master of. Each tag responds to the electro-magnetically transmitted beacons with an acoustic signal that identifies the tag. Multiple of the plurality of base stations, receive the acoustic signal of each tag. A location of each tag is estimated based on times of arrival of each acoustic signal of each tag at each of the multiple base stations, and based on location information of each of the multiple base stations.
