Abstract: The fixed-time reception control section carries out the reception process at first time to acquire first reception time data and compares the acquired first reception time data with the internal time. When a difference in time between the first reception time data and the internal time is greater than or equal to a first threshold, the fixed-time reception control section carries out the reception process at second time different from the first time to acquire second reception time data. The time correction section compares the acquired second reception time data with the internal time and corrects the internal time based on the second reception time data when a difference in time between the second reception time data and the internal time is smaller than a second threshold.
