Abstract:
A satellite signal reception device according to an aspect of the invention comprises a reception operation unit that executes a reception operation process to receive a satellite signal transmitted from a positioning information satellite and generates positioning information from the satellite signal. The satellite signal has precise and coarse information orbit periods containing precise and coarse orbit information respectively for the positioning information satellite. The reception operation unit executes the reception operation process in the precise orbit information period, uses the coarse orbit information period as a suspended reception period, and pauses at least a part of the reception operation process in the suspended reception period.
