RADIO RECEIVER AND ELECTRONIC TIMEPIECE

摘要

A radio receiver receives transmitted radio waves from positioning satellites, and includes: a signal amplification unit configured to amplify a received signal; an acquisition unit configured to acquire a satellite signal from the amplified signal; and a control unit configured to obtain predetermined information from the acquired satellite signal, determine a reception condition of transmitted radio waves based on the processing condition of at least one of the obtainment and the acquisition unit, and performs operation setting of a gain of the signal amplification unit according to the determined reception condition, wherein the control unit performs the operation setting so that the gain set in the operation setting when the reception condition is determined to be a first reception condition is smaller than the gain set in the operation setting when the reception condition is determined to be a second reception condition inferior to the first reception condition.

1. A radio receiver configured to receive and process a radio wave transmitted from a positioning satellite, the radio receiver comprising:
a signal amplification unit configured to receive a radio wave transmitted from a positioning satellite and amplify a signal of the received transmitted radio wave; an acquisition unit to which the signal amplified by the signal amplification unit is input, the acquisition unit being configured to acquire a satellite signal containing position information and date and time information from the signal; and a control unit configured to obtain at least one of the position information and the date and time information from the satellite signal acquired by the acquisition unit, determine a reception condition of the transmitted radio wave based on at least one of a processing condition of the obtainment and a processing condition of the acquisition unit, and perform operation setting of a gain of the signal amplification unit according to the determined reception condition, wherein the control unit performs the operation setting so that the gain set in the operation setting when the reception condition is determined to be a first reception condition is smaller than the gain set in the operation setting when the reception condition is determined to be a second reception condition inferior to the first reception condition.
