Auxiliary positioning method based on radio frequency recognition

Abstract

The invention discloses an auxiliary positioning method based on radio frequency recognition. The auxiliary positioning method includes the following steps that a radio frequency recognition auxiliary positioning receiver of a mobile terminal is connected with a radio frequency recognition tag in a covering range of the radio frequency recognition auxiliary positioning receiver, and positioning data including latest updating time information of the data are stored in the radio frequency recognition tag; when latest updating time of positioning data of the radio frequency recognition auxiliary positioning receiver of the mobile terminal is anterior to latest updating time of the positioning data of the radio frequency recognition tag, the positioning data stored in the radio frequency recognition tag are transmitted to the radio frequency recognition auxiliary positioning receiver of the mobile terminal; when the latest updating time of the positioning data of the radio frequency recognition tag is anterior to the latest updating time of the positioning data of the radio frequency recognition auxiliary positioning receiver of the mobile terminal, the positioning data stored in the radio frequency recognition auxiliary positioning receiver of the mobile terminal are transmitted to the radio frequency recognition tag. According to the auxiliary positioning method, the positioning speed and accuracy of satellite navigation can be improved.

Description

technical field [0001] The invention relates to an auxiliary positioning method, in particular to an auxiliary positioning method based on radio frequency identification (RFID). Background technique [0002] With the continuous development of wireless technology, location information service has received more and more attention. As a representative of location information services, the Global Positioning System (GPS) has been widely used in many fields such as vehicle navigation, engineering survey, marine rescue, aircraft navigation, and aviation remote sensing. GPS system is composed of space part, ground control system part and user equipment part. The system realizes the positioning and navigation functions of the target through a network composed of 24 orbiting satellites, ground control systems and receivers carried by users. The limitation of the GPS system is that the line of sight (LOS) needs to be maintained between the positioning target and the orbiting satelli...
