A reader geometry visualization tool for a geo-location system technician's personal computer is operative to display a map of an asset management environment. The technician interactively places and manipulates a distribution of tag transmission readers and any potential impairments to RF transmissions on the map. The locations of the readers (and any impairments) are coupled as input parameters to a mathematical model of a tag-based geo-location system. The performance of the map-parameterized geo-location system model is then computed as a geometric dilution of precision (gdop) value for the intended object coverage area. The computed (gdop) performance is visually characterized on the displayed map, as by way of different colors to indicate how accurately the proposed reader geometry will enable the system to locate objects anywhere in the coverage area.
A method of operating a computer workstation to configure a system for locating objects within a monitored environment, wherein transmissions from tags with said objects are to be detected at a plurality of spaced apart tag transmission readers for said monitored environment, and outputs of said tag transmission readers are processed by an object location processor to locate a tag and thereby its object within said monitored environment, said method comprising the steps of:
A method of enabling an object location system designer to specify where, relative to a monitored environment, a plurality of spaced apart tag transmission readers of said object location system for identifying locations of objects in said monitored environment are to be placed, wherein transmissions from tags coupled with said objects are to be detected at said plurality of spaced apart tag transmission readers, and outputs of said tag, transmission readers processed by an object location processor to locate a tag and associated its object within said monitored environment, said method comprising the steps of:
