I'll adopt Didier's notation here <shameless plug> Although it's marketed as an SDR for the BeagleBone, this project contains an open source 12+ channel software-defined GPS receiver: https://www.kickstarter.com/projects/1575992013/kiwisdr-beaglebone-software-defined-radio-sdr-with/
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> </shameless plug> _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
