Assisted positioning method based on radio frequency identification

The present invention discloses a method of locating an auxiliary radio frequency identification-based, comprising the steps of: a radio frequency identification RFID tag within its coverage assisted positioning receiver of the mobile terminal connection is established, the radio frequency identification tag including a stored latest updated data positioning time information data; when the last update time of the mobile terminal assisted positioning receiver RFID positioning data earlier than the last update time data of the positioning of the radio frequency identification tag, the radio frequency identification tag transmits location data to the mobile terminal stored in a radio frequency identifying the auxiliary positioning receiver; when the last update time data of the positioning radio frequency identification tag of the latest update time is earlier than a mobile terminal RFID positioning receiver auxiliary positioning data, the radio frequency identification secondary positioning of the mobile terminal stored in the positioning receiver data to the radio frequency identification tag. According to the present invention, it can improve the speed of satellite positioning and navigation accuracy.
