For an operation requiring high dynamic range and large bandwidth, the software receiver and host processor may not be able to manage a true real-time performance. However, available pre-processors like FPGA correlators (for correlation processing) and DSP processors (for FFT processing) do offer real-time capabilities.

These hardware add-ons fully match the RF front ends and can replace the software correlators available with software GPS receivers. We make C/A code and P-code versions in FPGA, DSP processing for FFT acquisition, and C/A code tracking, and mount these processors as daughter cards in the data-logging portion (PCI card) of the RF front end.
