SBX-4 Block Diagram
The SBX-4 accepts an analog input signal between 283.5 kHz and 325.0 kHz from an antenna into its front
end where it is filtered and converted to a digital output.
The Digital Signal Processor (DSP) demodulates GPS correction information from the digital stream. The
output of the SBX-4 is RTCM SC-104 DGPS correction data at a 3.3V CMOS interface level. Figure 1-3
provides a view of the block diagram. Figure 1-5 displays the block diagram.
