Abstract
A navigation device applied to a wireless identification tag includes a movable signal transceiver and an operation processor. The movable signal transceiver is adapted to transmit a detection signal and receive an actuation signal relevant to the detection signal. The operation processor is electrically connected to the movable signal transceiver. The operation processor is adapted to analyze the actuation signal to acquire relative position between the movable signal transceiver and the wireless identification tag, and generate a motion parameter in accordance with the relative position for moving the movable signal transceiver.
