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>
and jks.com appears to be slashdotted, very, very slow response
downloading the design doc.
Good luck to you folks with the board.
