SATELLITE RADIO WAVE RECEIVING DEVICE, ELECTRONIC TIMEPIECE, DAY/HOUR ACQUIRING METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a satellite radio wave receiving device, an electronic timepiece, a day/hour acquiring method and program that can acquire accurate day/hour information more reliably in a short period of time.SOLUTION: A satellite radio wave receiving device is equipped with receiving means that receives radio waves from satellites, demodulates signals and identifies each code in the demodulated signals as received codes; collating means that collates received codes from multiple satellites with assumed codes assumed to be received within the maximum deviation range set for the current day/hour acquired as the reception timing of the received codes, and acquires collation result information in association with a deviation within the maximum deviation range for each of the multiple satellites; collation result integrating means that integrates the collation results pertaining to the multiple satellites; deviation extent identifying means that identifies a deviation extent satisfying prescribed coincidence conditions between the received codes and the assumed codes on the basis of the integrated collation result information; and day/hour acquiring means that acquires day/hour information on the basis of the deviation extent that satisfies the prescribed coincidence conditions.SELECTED DRAWING: Figure 1
