Abstract
A positioning method and device used for solving the problems of the existing method for determining an integer ambiguity being relatively difficult and relatively time-consuming. During positioning, the method includes a receiving device determining a virtual phase measured value according to at least two received C-PRS signals (); determining a TOA measured value according to a received PRS signal (); determining a virtual integer ambiguity according to the TOA measured value and the virtual phase measured value (); and finally, determining the location of the receiving device according to the virtual integer ambiguity (). An integer ambiguity search space is reduced, and the integer ambiguity is determined faster, thus improving the efficiency of determining the location of the receiving device.
