Satellite signal reception device, and control method for a satellite signal reception device
Abstract:
A satellite signal reception device has a reception unit that receives a satellite signal transmitted from a positioning information satellite, and a reception control component that controls the reception unit to execute a reception process. The reception control component includes a satellite signal search component that searches for the satellite signal by means of the reception unit, a reception mode selection component that selects either a time mode or a positioning mode according to the number of satellites from which a satellite signal was captured by the satellite signal search component, a positioning process component that executes a positioning process of receiving the satellite signals and acquiring positioning information by means of the reception unit when the reception mode selection component selects the positioning mode, and a timekeeping process component that executes a timekeeping process of receiving the satellite signals and acquiring time information by means of the reception unit when the reception mode selection component selects the time mode.
