摘要：
A positioning apparatus that measures a current position by using measurement basis codes carried on satellite waves from a plurality of positioning satellites includes: a first phase error information generating unit that generates first phase error information indicating an error of a first phase on the basis of a frequency difference between a first frequency which is an estimated value of a receiving frequency of the satellite wave and a second frequency which is a frequency corresponding to a maximum value of a correlation value under a condition of the estimated phase; a second phase information generating unit that generates second phase information indicating a second phase by correcting a first phase information on the basis of the first phase error information; and a positioning unit that measures the current position on the basis of the second phase information on at least three of the positioning satellites.
