Abstract
A method of dividing a satellite signal into eight frequency points for processing includes the following steps: amplifying a satellite signal received by an antenna (S1); dividing the amplified satellite signal into radio frequency signals that includes eight frequency points in total, GPSL1, GPSL2, GPSL5, BDB1, BDB2, BDB3, GLNL1, and GLNL2, by a power divider circuit (S2); conducting a frequency mixing processing on five signals GPSL2, CPSL5, BDB2, BDB3, and GLNL2, and filtering the radio frequency signals that include eight frequency points in total, which include five frequency-mixed signals, GPSL2, GPSL5, BDB2, BDB3, and GLNL2, and three unmixed signals, GPS1, BDB1, and GN1 (S3); down-converting and A/D converting filtered eight-frequency-point radio frequency signals, outputting the signals to a baseband portion for a baseband signal processing (S4). This method reduces the power consumption, the size and the cost of the hardware.
