Method and apparatus for installing and/or determining the position of a receiver of a tracking system
First Claim
1. A method of installing and determining the positions of a plurality of receivers of a tracking system adapted to receive a beaconing signal from a beacon, said tracking system to be used to determine the location of said beacon based on information gathered by said plurality of receivers as to the position of said beacon relative to the positions of said plurality of receivers based on receipt of said beaconing signal at said plurality of receivers, said method comprising the steps of:
- (1) positioning a tracking device at a first location;
(2) recording coordinates of said first location with said tracking device as a base location;
(3) moving said tracking device to another location for installing one of said plurality of receivers;
(4) recording coordinates of said another location with said tracking device as said location of said one of said plurality of receivers wherein said another location is recorded in coordinates relative to said base location; and
(5) repeating steps (1)-(4) for each of said plurality of receivers.

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. The installer then walks to the location where the first receiving device will be installed while the tracking device tracks his or her movement or position. At the first installation location, the installer causes the tracking device to record this position as the position of the first receiver installed. The process is repeated for each receiver to be installed.

17. A method of installing and determining the positions of a plurality of receivers of a tracking system adapted to receive a beaconing signal from a beacon, said tracking system to be used to determine the location of said beacon based on information gathered by said plurality of receivers as to the position of said beacon relative to the positions of said plurality of receivers based on receipt of said beaconing signal at said plurality of receivers, said method comprising the steps of:
-
(1) recording a first location coordinates as a base location; (2) moving from said base location to another location selected for installing a one of said receivers; (3) recording said another location coordinates as said location of said one of said plurality of receivers wherein said another location coordinates is recorded in coordinates relative to said base location; and (4) repeating steps (1)-(3) for each of said plurality of receivers.
