Abstract: A satellite radio signal receiver includes a receiving section which receives radio signals from satellites and demodulates the signals to identify bits of the demodulated signals as received bits; and a processor. The processor compares each received bit of the satellites with estimated bits which are estimated to be received within a possible deviation range from a current date and time acquired as a reception timing of the received bit to obtain comparison result information between the received bits and the estimated bits in relation to deviations within the possible deviation range with respect to each of the satellites, integrates the comparison result information on the received bits of the satellites, specifies a deviation that satisfies a match condition of the received bits and the estimated bits based on the integrated comparison result information, and acquires date and time information based on the deviation that satisfies the match condition.

Abstract: A radio-controlled timepiece includes: a radio wave reception unit that receives satellite waves and extracts an incoming code sequence encoded in the received satellite waves; a counter unit that counts a date/time of the radio-controlled timepiece; and a processor that: generates an expected code sequence containing at least a portion of a preamble code and a code generated on the basis of the date/time counted by the counter unit that are expected to be part of the incoming code sequence that is extracted, detects a match between the expected code sequence that has been generated and the incoming code sequence by sequentially comparing the expected code sequence with the incoming code sequence, and acquires a present date/time, as indicated by the satellite waves, in accordance with a detection timing of the match, as measured by the data/time counted by the counter unit.

Abstract: 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.
