Disclosed is a position measuring method capable of measuring a position within a short time. The position measuring method includes the following steps of: receiving data acquisition time from the other terminal; receiving data from the other terminal if the received data acquisition time is later; and determining the position of an information terminal when it is possible to determine the position of the information terminal on the basis of the received data. Therefore, the information terminal can improve the accuracy of the position measurement by receiving position information, satellite information and cell ID information etc of the other terminal from the other terminal, and can reduce initial position information receiving time (TTFF, Time To First Fix) dramatically.
