Abstract
A reception control unit of an electronic timepiece includes a satellite-capturing control unit configured to search for a preferential search satellite more preferentially than the other position information satellites, the preferential search satellite being the position information satellite having a stored satellite number, a reception-state determining unit configured to determine, at timing of an end of the search for the preferential search satellite, whether a number of the captured position information satellites is equal to or larger than a predetermined number; a reception-stop control unit configured to stop a reception processing when the reception-state determining unit determines that the number of the position information satellites is smaller than the predetermined number; and a storage control unit configured to store the satellite number of the captured position information satellite in the satellite-number storing unit.
