Abstract
A positioning apparatus for positioning a current position based on satellite signals from positioning satellites includes: satellite signal receiving means, correlation information generating means, tentative code peak position information generating means, statistical processing range information generating means, statistical information generating means for generating statistical information by performing a statistical processing of the correlation values within the statistical processing range for each partial range specified as a limited range rather than the statistical processing range, beginning position information generating means, and direct wave code peak corresponding position information generating means for generating direct wave code peak corresponding position information which indicates a direct wave code peak corresponding position corresponding to a direct wave code peak, which is the maximum correlation value between the direct wave and the replica satellite signal, based on the beginning position information.
