Abstract
An object localization and tracking system includes a plurality of tags that are placed on respective objects. Each tag includes a transceiver and at least three orthogonal antennas to receive RF energy in a three dimensions. The tag transceiver and antennas cooperate with other tag antennas and transceivers to establish a tag (object) RF network. Each tag further includes a microprocessor, and sensors that determine tag position and relative position of other tags in the tag RF network. A user interface is connected to one of the tag microprocessors. A predetermined algorithm, which describes desired positional information for each tag in the RF network (and its corresponding object), is input into one of the microprocessors through the user interface. A tag audible or visual alert activates when the actual positional information of the tag (and the attached object) do not correspond to the desired positional information.
