The Venus822A is a high-performance GPS / GNSS
baseband processor intended for GPS / Beidou or
GPS / GLONASS applications. It contains all the
baseband function required for GPS / Beidou and
GPS / GLONASS signal acquisition, tracking, and
navigation solution. The Venus822A is designed to
allow easy integration of GPS / Beidou or GPS /
GLONASS into application systems.
A dedicated massive-correlator signal parameter
search engine enables rapid search of all available
satellites and acquisition of very weak signals. An
advanced track engine allows weak signal tracking
and positioning in severe environments such as
urban canyons and under deep foliage.
A complete low-cost high-performance GPS /
Beidou or GPS / GLONASS receiver can be built
with Venus822A, a compatible GPS / Beidou or
GPS / GLONASS RF front-end, and a small number
of external components.

FUNCTIONAL DESCRIPTION
Figure-2 Baseband Processor Functional Diagram
The Venus822A implements all the needed function for GPS/Beidou and GPS/GLONASS signal acquisition,
tracking, decoding, and navigation solution. It is optimized for GPS/Beidou or GPS/GLONASS applications
requiring high performance. Major blocks within the chip are: GPS/GNSS signal processing engine, 32bit
RISC processor, peripheral interface, and memory.
RF Interface
The RF interface supports single-ended IF signal in sign/magnitude format and sampling frequency of
16.367667MHz with +/-0.5ppm accuracy for GPS/Beidou, and 24.552MHz with +/-0.5ppm accuracy for
GPS/GLONASS.
GPS/GNSS Signal Processing Engine
The signal-processing engine comprise of a signal parameter search engine and a track engine. Both
implement carrier frequency wipe-off, pseudorandom code removal, plus coherent and incoherent integration
required for indoors high-sensitivity signal processing.
The signal parameter search engine can be configured to search full code space and several frequencies
simultaneously, or full code space of all satellites simultaneously. Massive correlator design allows extremely
high signal acquisitions speed and high sensitivity performance.
32bit RISC
The internal 32bit RISC is a 7-stage pipelined processor. The processor handles all time-critical GPS/GNSS
related functions, management controls, and navigation solutions.
