Satellite radio-wave reception device, radio clock, information acquisition method, and recording medium

A satellite radio-wave reception device includes a demodulator. A demodulator determines an assumption code, identifies a plurality of reception codes from a received radio wave, collates an assumption code in a deviation range, which is previously set with respect to reception timing of the reception codes, and each of the reception codes, holds information related to a collation result in each deviation amount with respect to the plurality of reception codes, determines one of correspondences and noncorrespondences, the number of which one is larger, as matching in each code block, and identifies a deviation amount in which the integrated value of matching corresponding to an integrated value of the number of matching codes in a plurality of code blocks in each deviation amount satisfies a predetermined matching condition.
