Location and tracking of people with combined use of RF infrascture and dead reckoning modules

摘要

A system for tracking persons and other assets in a structure, having a multi-function tracking tag and a network of fixed RF receivers forming a gateway array. The location of the person being tracked is calculated by a computer using an algorithm that weights each separate signal according to the probability of its accuracy, thus using data with the least error. A preferred algorithm is shown in FIG. 2.
