Abstract: 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.

Abstract: A universal multi-channel receiver for receiving and processing signals from different navigation systems is provided. The universal receiver is implemented as an ASIC receiver with a number of universal channels. The receiver with universal channels is capable of receiving and processing signals from navigation satellites located within a direct access zone. The universal receiver has a plurality of channels that share the same memory. The universal receiver can determine its coordinates using any of the existing navigation systems (GPS, GLONASS, Beidou and GALILEO). The receiver can receive and process any (PN) signals.
