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 signals, and converts IF
analog signals into digital signals required for NebulasIV
TM
chip.
NebulasIV
TM
SoC
NebulasIV
TM
is UNICORECOMM’s new generation high precision GNSS SoC with 22 nm
low power design, supporting all constellations, multiple frequencies and 1408 super
channels. It integrates a dual-core CPU, a high speed floating point processor and an
RTK co-processor, which can fulfill the high precision baseband processing and RTK
positioning independently.
External Interfaces
The external interfaces of UM960L include UART, I
