Satellite Signal Receiving Device, Electronic Timepiece, and Satellite Signal Receiving Method
First Claim
1. A satellite signal receiving device comprising:
- a reception unit is configured to search for positioning information satellites including a GNSS satellite used in a global navigation satellite system and an RNSS satellite used in a regional navigation satellite system, and receive a satellite signal transmitted from a satellite locked onto by the search;
a reception control unit is configured to control the reception unit; and
a region determination unit is configured to determine whether or not the current location is in a region where a satellite signal transmitted from the RNSS satellite can be received;
the reception control unit prioritizing searching for an RNSS satellite when the region determination unit determines the current location is in a region where satellite signal transmitted from the RNSS satellite can be received.
