The baseband processing block is responsible for processing the down-converted and digitized signal in order to provide GNSS observables: code pseudo-ranges and carrier phase measurements, as well as navigation data. Additional information such as Doppler frequency, Carrier to Noise ratio, lock indicators can also be provided. In most GNSS receivers’ architectures, the baseband processing relies on independent channels that track each satellite signal autonomously. Then the information from each channel is integrated to derive a navigation solution.
Block Diagram
The baseband processing block is usually replicated over several channels. Each channel processes a given signal from a given satellite in order to provide GNSS observables and navigation data. A generic diagram of a single channel within the Baseband Processing block is depicted in the following figure.
