Abstract:
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) displaying on said computer workstation a map of said monitored environment; (b) identifying on the map displayed in step (a) potential locations of a plurality of said tag transmission readers; (c) generating a mathematical model of said system using said potential locations of said plurality of said tag transmission readers identified on said map in step (b); (d) characterizing, on said map of said monitored environment, the ability of a system represented by said mathematical model generated in step (c) to identify locations of objects within said monitored environment; measuring the geo-location performance of said system represented by said mathematical model generated in step (c) in terms of a geometric dilution of precision (gdop); and visually characterizing gdop accuracy as an estimate of performance of the system model.
