Satellite signal receiving device, electronic timepiece, and satellite signal receiving method

摘要

A satellite signal receiving device including: a reception unit is configured to searche 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 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 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.

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; wherein the reception control unit is configured to execute a timekeeping reception process that acquires current time information from the satellite signal, and a positioning reception process that acquires positioning information based on the satellite signal; and when the region determination unit determines the current location is in a region where satellite signal transmitted from the RNSS satellites can be received, the reception control unit prioritizes searching for the RNSS satellite during the timekeeping reception process, and does not prioritize searching for the RNSS satellite during the positioning reception process.
