Abstract
Correlation calculation is performed on a received signal of a GPS satellite signal as a positioning signal based on a given predicted frequency. Then, an erroneous frequency of the predicted frequency is estimated using carrier phase of the GPS satellite signal based on a result of the correlation calculation. Then, whether or not the erroneous frequency satisfies a predetermined allowable condition is determined, and whether or not an electronic apparatus is in a non-translational movement state in which the electronic apparatus moves while changing the location thereof with respect to a body of the user is determined.
