Abstract: Disclosed herein is a receiver including: a first mixer adapted to mix satellite signals from first and second satellites and a first local oscillation signal so as to convert a carrier frequency of the satellite signals into a lower first intermediate frequency; a second mixer adapted to mix a satellite signal of the second satellite frequency-converted by the first mixer and a second local oscillation signal so as to convert the first intermediate frequency of the frequency-converted satellite signal from the second satellite into an even lower second intermediate frequency; and a first frequency divider adapted to generate the second local oscillation signal by dividing a frequency of the first local oscillation signal.
