Abstract
A method of calculating the position of a moving body includes: detecting a movement direction of the moving body; calculating a velocity vector of the moving body using a detection result of an acceleration sensor installed in the moving body; correcting the velocity vector using the movement direction; and calculating the position of the moving body using the corrected velocity vector.
