ABSTRACT:
A positioning device comprising: a peak frequency determination section which determines a peak frequency which is a reception frequency corresponding to a maximum correlation value of a specific positioning base code replica and a positioning base code carried on a radio wave from a specific transmission source; a reference frequency calculation section which calculates a low frequency which is a frequency lower than the peak frequency and a high frequency which is a frequency higher than the peak frequency; a reference correlation value calculation section which calculates the correlation value corresponding to the low frequency and the correlation value corresponding to the high frequency; a corrected peak frequency calculation section which calculates a corrected peak frequency based on the correlation value corresponding to the peak frequency, the peak frequency, the correlation value corresponding to the low frequency, the low frequency, the correlation value corresponding to the high frequency, and the high frequency; and a radio wave reception section which receives the radio wave using the corrected peak frequency.
