Virtual anchor radio based positioning method, and a terminal device

The present invention discloses a kind of virtual anchor radio based positioning method, and a terminal device, the method comprising: when the effective targeting is met, obtains and stores the positioning data, the radio station transmitting the signal while the signal received multipath transmission and tracking, the distance information calculated and saved for each propagation path, and calculates and stores the position information of the virtual image of each transmitting station signal propagation path, and the positioning data of each path signal transmitting station distance information; when the effective targeting insufficient, transmitting station selection signals from the multipath virtual image as the virtual image positioned at least one virtual anchor, and according to the valid target and the at least one anchor positioned virtual current position information is obtained. The present invention is in a multipath rich scene (e.g., indoors, dense urban, etc.), radio signal transmitters actual recorded continuously multipath virtual anchor in combination with other active targeting positioning, full use of the multi-path information, reduces signal reflection and diffraction caused by the positioning error, while an effective solution to the shortage of the number of significant problems anchor point.
