1. A rotation angle calculation device comprising:
a sensor configured to output a detection signal depending on rotation of a rotating body;
a rotation angle calculation unit configured to calculate a rotation angle of the rotating body, based on the detection signal;
a reception unit configured to receive calibration data for calibration of a rotation angle of the rotating body calculated by the rotation angle calculation unit;
a storage unit configured to store the received calibration data;
a correction unit configured to correct a rotation angle of the rotating body calculated by the rotation angle calculation unit with the calibration data stored in the storage unit; and
a transmission unit configured to transmit rotation angle data indicating the rotation angle calculated by the rotation angle calculation unit and not corrected by the correction unit and to also transmit time difference data relating to a time difference after having captured the detection signal from the sensor until transmitting the rotation angle data.
