Abstract
A satellite signal reception device includes: a local signal generator that generates a signal while switching between a signal having a first local frequency corresponding to a first positioning satellite signal and a signal having a second local frequency corresponding to a second positioning satellite signal based on a reference clock signal; and a frequency converter that converts a reception signal of the first positioning satellite signal into a first intermediate frequency signal by multiplying the reception signal of the first positioning satellite signal by the signal having the first local frequency, and converts a reception signal of the second positioning satellite signal into a second intermediate frequency signal of which at least a part of a converted frequency band is in common with the first intermediate frequency signal multiplying the reception signal of the second positioning satellite signal by the signal having the second local frequency.
