Zusammenfassung: | A method for receiving and processing satellite navigation signals includes receiving the navigation signals; converting the navigation signals into digital signals; providing a clock signal to all channels that process the digital signals; generating frequency division signals; selecting a channel frequency division signal from the frequency division signals based on which ADC is used to convert the satellite navigation signals into digital signals; connecting the channel to the ADC; generating code frequency signal and base carrier frequency signal using a net accumulation signal; processing the digital signal in the channel to produce digital quadrature signal components of the digital signal based on the code frequency signal and the base carrier frequency signal; using a tick signal that represents 2N×clock signal as a temporary time scale for control of the channels for determining digital signal phase differences between the channels; and outputting coordinates based on the quadrature components. |
