摘要： A dual mode satellite signal receiver capable of supporting at least two global navigation satellite systems and a satellite signal receiving method are provided. The dual mode satellite signal receiver comprises a frequency synthesizer for generating a local oscillator signal based on a reference frequency; a mixer for mixing the local oscillator signal with a satellite signal and outputting the mixed signal as a signal of an intermediate frequency band; a first filter for filtering the signal output from the mixer to reject an image signal and output only an actual signal; a second filter for filtering the actual signal to output only a predetermined bandwidth according to a positioning mode; and an amplifier for amplifying the second filter output signal to a predetermined level and outputting the amplified signal.
