Abstract: An electronic timepiece includes a display section, a display control section, a reception section, a clock section, a timing section, a leap second acquisition section, a time correction section that corrects internal time information by using time information acquired by the timing section, and a leap second correction section that corrects the internal time information by using leap second information acquired by the leap second acquisition section. In a case where the operation of the timing section is followed by the operation of the leap second acquisition section, the time correction section corrects the internal time information by using the time information acquired by the timing section, and the display control section causes the display section to display, before the leap second acquisition section acquires the leap second information, time based on the internal time information corrected by the time correction section.

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.

Abstract: An electronic timepiece enables a simple construction, and an electronic device has the electronic timepiece. A wristwatch 1 has a button A 6; a mode setting unit 32 that sets the operating mode of the wristwatch 1 based on an input operation of the button A 6. Based on the continuous input time that the button A 6 is operated continuously, the mode setting unit 32 changes the operating mode between a timekeeping mode that receives satellite signals from one or more GPS satellites and adjusts the internal time information based on time information contained in the received satellite signal(s); and a positioning mode that receives satellite signals from three or more GPS satellites and adjusts the internal time information based on time information and positioning information contained in the received satellite signals.

Abstract: An electronic timepiece can determine the reception state in detail, and can display the reception state with high precision. A GPS wristwatch 1 has a reception unit that receives a satellite signal transmitted from a positioning information satellite; a reception level calculating unit 47 that calculates a reception level from the signal strength of the satellite signal; and a reception level display unit 48 that displays the reception level calculated by the reception level calculating unit 47. The reception level calculating unit 47 selects a specific number of satellite signals received from the positioning information satellites in order of greatest signal strength, and calculates the reception level from the signal strengths of the selected satellite signals.

Abstract: A satellite signal reception device can reliably execute a satellite signal reception process. The satellite signal reception device has a reception time setting unit 71 that sets a reception time; a timekeeping unit that keeps internal time; and a scheduled reception control unit 72 that executes a time-based reception process that operates the reception unit when the time kept by the timekeeping unit reaches the reception time. By having a scheduled reception control unit 72, the reception process can be executed when the internal time goes to the reception time set by the reception time setting unit 71. The reception process is therefore executed once a day. The satellite signal reception process can therefore be executed reliably without being affected by how the device is used, the season, weather, or other factors.

Abstract: A satellite signal reception device that can desirably receive satellite signals has a charge state detection circuit 43 and a voltage detection circuit 44 that detect if the satellite signal reception device is outdoors, and a control circuit 40. If the satellite signal reception device is determined to be outdoors based on the detection result from the charge state detection circuit 43 and voltage detection circuit 44, the control circuit 40 operates a GPS reception circuit 30. If an indoor state in which the satellite signal reception device is determined to not be outdoors continues for at least a predetermined specific time, the control circuit 40 operates the GPS reception circuit 30 at a preset scheduled reception time.

Abstract: An electronic timepiece can improve the frequency of satellite signal reception and reduce power consumption. Such timepiece, e.g., a wristwatch has a GPS device that executes a reception process that locks onto a GPS satellite and receives satellite signals; a reception control unit that controls the reception process; and a solar panel that detects illuminance. The reception control unit includes an illuminance-based reception control unit that runs a reception process based on the detected illuminance, and a scheduled reception control unit that runs a reception process when a preset scheduled time is reached. The illuminance-based reception control unit stops reception when a satellite is not locked onto within a first locking time, and the scheduled reception control unit stops reception when a satellite is not locked onto in a second locking time that is shorter than the first locking time.
