PROBLEM TO BE SOLVED: To provide radio terminal equipment which measures a present position precisely even in a case that distinction of signals from base stations is difficult (an area or the like in which the same PN offset value is used repeatedly). SOLUTION: This radio terminal equipment is provided with a receiving means for receiving signals from a plurality of radio stations, a receiving timing analyzing means for analyzing receiving timing of the signal received by the receiving means, a radio station selecting means for selecting a radio station to be used for position calculation, and a position calculating means which calculates a position of a receiving point by using the receiving timing of the signal from the selected radio station. The radio station selecting means selects a radio station to be used for position calculation in such a manner that a signal from at least any one radio station is not used when receiving timings of signals from at least the two radio stations cannot be distinguished. |
