In a baseband process circuit unit, a demodulation unit demodulates a received satellite signal which carries a navigation message to obtain a demodulated data. Further, an error bit detection unit detects an error bit from among the demodulated data using a parity code included in the demodulated data. An inconsistent bit detection unit detects an inconsistent bit by comparing the demodulated data with prescribed comparison data. An adoption determination unit determines whether or not to adopt the demodulated data, based on a difference between the error bit and the inconsistent bit. In addition, a correction unit corrects the demodulated data, in a case where the demodulated data is determined to be adopted by the adoption determination unit.
