Abstract
A timepiece including a GPS receiver that receives a radio wave from a positioning satellite, a time counter that performs a time count operation, and a processor, the processor being configured to: corrects a time count of the time counter in accordance with time and date information included in the radio wave from the positioning satellite received by the GPS receiver; acquires a temperature in the timepiece; acquires a voltage of a battery; and controls a receive operation at the GPS receiver in accordance with the temperature and the voltage.
Claims9
A timepiece comprising:
- a GPS receiver that receives a radio wave from a positioning satellite;
- a time counter that performs a time count operation;
- and
- a processor,
- wherein the processor:
- corrects a time count of the time counter in accordance with time and date information included in the radio wave from the positioning satellite received by the GPS receiver;
- acquires a temperature in the timepiece;
- acquires a voltage of a battery;
- and
- controls a receive operation at the GPS receiver in accordance with the temperature and the voltage.
A method for controlling a timepiece, the timepiece comprising a GPS receiver that receives a radio wave from a positioning satellite, a time counter that performs a time count operation, and a correction unit that corrects a time count obtained by the time counter in accordance with date and time information included in the radio wave from the positioning satellite received by the GPS receiver, the method comprising:
- acquiring a temperature in the timepiece;
- acquiring a voltage of a battery;
- and
- controlling a receive operation at the GPS receiver in accordance with a result of measurement of each of the temperature and the voltage.
A non-transitory storage medium having stored thereon a program readable by a computer incorporated into a timepiece, the timepiece comprising a GPS receiver that receives a radio wave from a positioning satellite, a time counter that performs a time count operation, and a correction unit that corrects a time count obtained by the time counter in accordance with date and time information included in the radio wave from the positioning satellite received by the GPS receiver, the program has the computer to function as a controller for:
- acquiring a temperature in the timepiece;
- acquiring a voltage of a battery;
- and
- controlling a receive operation at the GPS receiver in accordance with a result of measurement of each of the temperature and the voltage.
