Abstract: A position calculation device which includes a sensor unit having an acceleration sensor and a gyro sensor is rotated around a vertical direction as an axial center in a state where a plane defined by a first axis and a second axis of the acceleration sensor is substantially perpendicular to the vertical direction. The bias of each of the first axis and the second axis of the acceleration sensor is calculated using a detection value of the sensor unit obtained during rotation.
