Abstract:
    This invention relates to indoor wireless sensor network technique, which is characterized by the following: the badge of this invention is movable and reader is fixed; position computer is to receive badges and reader distance data from different times through connector wire; setting signal alignment and distance computation module at badge, reader and connector CPU; setting computation module at computer and using radio frequency and super wave signals from badge time of arrival to compute distance; using extensive Kalman filter to compute position.
