PROBLEM TO BE SOLVED: To provide a positioning system, or the like capable of calculating an original code peak position by eliminating the influence of multipath quickly without performing time integral to a correlation result. SOLUTION: The positioning system comprises a tentative code peak position information generation means; a statistics processing range information generation means for generating statistics processing range information; a statistics base information generation means for performing statistics processing to a correlation value a1, or the like within a statistics processing range A for each partial range W to generate statistics base information for indicating a statistics base value b1, or the like; a statistics information generation means for generating statistics information for indicating a change in the statistics base value b1, or the like; a rising position information generation means for generating rising position information for indicating the rising position of a code peak, based on statistics information; and a direct wave code peak correspondence position information generation mean, and the like for generating direct wave code peak correspondence position information for indicating a direct wave code peak correspondence positionα2 corresponding to a direct wave code peak that is the maximum value of the correlation value between a direct wave Sd and a pseudo satellite signal, based on the rising position information.
