I'll adopt Didier's notation here

Although it's marketed as an SDR for the BeagleBone, this project contains an open source 12+ channel software-defined GPS receiver:

It's very easy to experiment with GPS signal processing by changing the C++ code on the Beagle or the Verilog on the FPGA (provided you have the stomach to install the Xilinx Vivado design tools). For example, I learned a lot by adding decimation to the correlation code. This speeds up strong signal acquisition because the FFTs can be smaller. The SDGPS is from Andrew Holme's Homemade GPS Receiver project <aholme.co.uk/GPS/Main>
