A position calculating method includes: estimating a reception frequency and a code phase related to reception of a positioning signal from a positioning satellite as an estimated measurement; acquiring a reception frequency and a code phase on the basis of the positioning signal received from the positioning satellite; setting a value of an error parameter as an observed measurement, which is used in position calculation using a Kalman filter, on the basis of a difference between the observed measurement and the estimated measurement; and calculating a position by performing the position calculation using the error parameter value.
