Method of tracking at least one mobile unit comprising integrated radio/pseudolite transceiver and laser detector by utilizing stationary self-positioning radio transceiver and stationary laser transmitter

摘要

A method of tracking at least one mobile unit utilizing a radio and light based 3-D positioning system comprising a stationary self-positioning radio (pseudolite) transceiver, a stationary laser transmitter positioned in a location with known coordinates, a wireless link, and a display. The method comprises: (A) determining position coordinates of the stationary self-positioning radio (pseudolite) transceiver; (B) broadcasting at least one internal radio signal by using the self-positioning radio (pseudolite) transceiver via the wireless link; (C) generating at least one laser beam by using the stationary laser transmitter; (D) broadcasting at least one laser beam; (E) receiving a plurality of external radio signals, receiving at least one internal radio signal by using the wireless link, and detecting at least one laser beam by using integrated radio (pseudolite) transceiver/laser detector; (F) determining 3-D position coordinates of at least one mobile unit comprising the integrated radio (pseudolite) transceiver/laser detector; (G) broadcasting 3-D position coordinates of at least one mobile unit via the wireless link; and (H) receiving and displaying the position coordinates of at least one mobile unit.
