The present disclosure provides localization methods and a system using the same. One of the methods includes: broadcasting a ranging frame in a awake state of a localization tag; obtaining a response frame returned by the first anchor according to the ranging frame; updating the ranging anchor list according to the response frame; and calculating a distance between the localization tag and the first anchor based on a time of broadcasting the ranging frame, a time of receiving the response frame, the time of the first anchor receiving the ranging frame, and the time of the first anchor transmitting the response frame. In such a manner, the localization tag is enabled to switch the anchor for ranging in time according to the updated ranging anchor list during movement, thereby automatically ranging with the nearby anchor.
