发明名称 Satellite radio signal receiver, electronic timepiece, date and time information acquiring method and recording medium
摘要 A satellite radio signal receiver includes a receiving section and a processor. The receiving section receives a radio signal from a satellite and demodulates the signal to identify each received bit of the signal. The processor compares the identified received bit with estimated bits which are estimated to be received within a possible deviation range set for a current date and time acquired as a reception time of the received bit, so as to obtain information on comparison result in relation to a deviation from the current date and time. The processor detects the deviation which satisfies a predetermined match condition of comparison results for received bits. The processor acquires date and time information based on the detected deviation which satisfies the predetermined match condition.
