RF Part
The receiver gets filtered and enhanced GNSS signal from the antenna via a coaxial
cable. The RF part converts the RF input signals into the IF signal, and converts IF
analog signal into digital signals required for NebulasII (UC4C0) digital processing.
2.
NebulasII SoC (UC4C0)
The UM4B0 incorporates the processing from the NebulasII (UC4C0),
UNICORECOMM’s new generation high precision GNSS SoC with 55nm low power
design, which supports up to 12 digital intermediate frequency or 8 analog
intermediate frequency signals and can track 12 navigation signals with 432 channels.
3.
