发明名称 Radio controlled timepiece
摘要 A radio controlled timepiece includes a GPS reception processing unit that searches for and captures a signal included in radio waves from a positioning satellite, demodulates and decodes the captured signal to acquire the data corresponding to acquisition target information in data transmitted from the positioning satellite, acquires the acquisition target information using the acquired data, holds a failure history related to acquisition of the data with respect to each captured signal, suspends acquisition of the data from a signal having a reception level determined to be at least equal to a predetermined reference level based on the failure history, and ends acquisition of the data when the number of signals from which the data is to be acquired after search for the signal is ended under a predetermined condition becomes smaller than the number of signals necessary in acquiring the acquisition target information.

主权项 1. A radio controlled timepiece that receives radio waves transmitted from a positioning satellite, the radio controlled timepiece comprising a GPS reception processing unit configured to search for and capture a signal from a positioning satellite, the signal being included in received radio waves, demodulate and decode the captured signal, to acquire data corresponding to acquisition target information in data transmitted from the positioning satellite, acquire the acquisition target information, using the acquired data, hold a failure history related to acquisition of the data with respect to each captured signal, suspend acquisition of the data from a signal having a reception level determined to be at least equal to a predetermined reference level based on the failure history, and end acquisition of the data when the number of signals from which the data is to be acquired after search for the signal is ended under a predetermined condition becomes smaller than the number of signals necessary in acquiring the acquisition target information.
