Satellite Signal Receiving Device, Electronic Timepiece and Satellite Signal Receiving Method |
| 摘要 |
A satellite signal receiving device includes a receiving circuit that receives a satellite signal transmitted from a position information satellite, a solar cell that converts light energy into electrical energy, and a control section that controls the receiving circuit and starts a receiving process of the satellite signal, when illuminance of light incident on the solar cell is equal to or greater a preset illuminance threshold within a range of equal to or greater than 1,000 Lx and less than 5,000 Lx. |
