Abstract
A radio frequency positioning system is described that determines identity and positional data of numerous objects. The system includes a plurality of spread spectrum radio transceivers where at least one transceiver is positioned on each of the numerous objects. At least three spread spectrum radio transceivers transmit to and receive signals from the plurality of radio transceivers. A signal processor is coupled to the spread spectrum radio transceivers and determines the identity and the positional data of the objects.
