Abstract:
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.
