Abstract: An electronic timepiece includes a display section capable of displaying reception state information based on the strength of a received satellite signal or the number of captured satellites during the execution of a reception process. In a case where a predetermined period has elapsed with no acquisition of time information or position information since the reception process started, the reception state information is displayed on the display section, and in a case where the time information or the position information has been successfully acquired within the predetermined period since the reception process started, the reception state information is not displayed on the display section but the reception process is terminated.

Abstract: An electronic timepiece includes a clock circuit, a receiver that receives radio waves from positioning satellites, an operation receiving unit, and a control unit constituted by a CPU and a module controller. The control unit makes the receiver perform either one of a date and time reception process that attempts to obtain date and time information and a positioning reception process that attempt to obtain information needed to obtain the current location; and, when a prescribed input operation that affects the current region setting is received, the control unit makes the receiver perform the positioning reception process at least once in the reception operations that are performed after receiving the prescribed input operation before a prescribed location updating event that determines a current location of the electronic timepiece occurs.

Abstract: A satellite radio wave receiving device including: one or more controllers configured to: continually perform calculation of a current location based on radio waves from positioning satellites received by a receiver; determine whether an action state of the satellite radio wave receiving device detected by an action detection sensor has changed to a stop state; in response to determining that the action state of the satellite radio wave receiving device has changed to the stop state, interrupt the calculation of the current location by causing the receiver to interrupt reception of the radio waves; and cause an output device to perform an interruption notification operation for notifying that the calculation of the current location is being interrupted.

Abstract: A radio-controlled timepiece is shown including the following. A timekeeping unit keeps date and time. A date/time obtaining unit obtains date/time information from outside to correct the date and time of the timekeeping unit. A preliminary notice information obtaining unit obtains from outside preliminary notice information regarding whether leap second adjustment in which a leap second is inserted or deleted is executed. A date/time obtaining necessity setting unit sets whether the date/time information needs to be obtained based on history of obtaining the date/time information. The date/time obtaining necessity setting unit sets that the date/time information needs to be obtained when the preliminary notice information is not obtained by the adjustment possible date/time or the leap second adjustment is executed at the adjustment possible date/time, and does not change setting when the preliminary notice information is obtained and the leap second adjustment is not executed.

Abstract: A satellite signal receiving device having a receiver circuit that receives a satellite signal transmitted from a positioning information satellite further includes a solar cell that converts light energy to electrical energy; a generating state detection circuit that detects a generating state of the solar cell to obtain a detection value, which is a power generating evaluation time, which is a time during which the solar cell output is continuously in a high illuminance state; and a control circuit that controls the receiver circuit and the generating state detection circuit, sets a threshold value for the power generating evaluation time, and compares the detection value with the threshold value and operates the receiver circuit when the detection value is greater than or equal to the threshold value. The control circuit changes the threshold value for the power generating evaluation time when satellite signal reception failed.

Abstract: An electronic timepiece comprises a receiver configured to receive satellite signals containing time information from positioning information satellites; an interface member; a timekeeping reception controller configured to execute a timekeeping reception process in response to a timekeeping reception operation of the interface member; and a positioning reception controller configured to execute a positioning reception process in response to a positioning reception operation of the interface member. The timekeeping reception controller starts the timekeeping reception process if the interface member is operated continuously for a first set time, and continues the timekeeping reception process if operation of the interface member is released before a second set time passes, the second set time being longer than the first set time, and operation switches from the timekeeping reception process to the positioning reception process if the interface member is operated for the second set time.

Abstract: An electronic timepiece has a reception unit that receives satellite signals; a power supply including a battery; a remaining battery capacity detector that detects the remaining battery capacity of the power supply; an interface member; a timekeeping reception controller; and a positioning reception controller. If the user performs a positioning reception operation, the positioning reception controller does not execute a positioning reception process if the remaining battery capacity is less than a first threshold. If the timekeeping reception operation is performed, the timekeeping reception controller executes a timekeeping reception process if the remaining battery capacity is less than the first threshold.

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.
