Abstract: The present invention pertains to the installation and positioning of the receivers of a wireless tracking system. In such a system, a wireless beaconing device transmits a signal that can be detected by a plurality of wireless receivers positioned at various known locations. Each wireless receiver records information derived from the signal from which it can make an estimate of the distance or relative position of the beaconing device. A controller correlates the information received from the multiple receivers and uses it to estimate the location of the individual. In such systems, the accuracy of the estimated position of the beaconing device depends on the accuracy to which the positions of the receivers are known. A technique is disclosed in which an installer carries a tracking device that can track the person's position and/or movements. The installer starts at a base location and resets the tracking device to cause the tracking device to record this position as the base position.
