    Abstract: Provided are a position tracking system and a position tracking method. The position tracking system includes at least one target node, a plurality of reference nodes having position information, and a position determination device. An arbitrary reference node among the reference nodes and the target node utilize a distance measurement message to measure a first time of arrival (TOA) and then transmit the first TOA to the position determination device. At least two other reference nodes adjacent to the arbitrary reference node and the target node listen to the distance measurement message to measure a second TOA and then transmit the second TOA to the position determination device, in order to track a position of the target node.
