- squantor 19d agoI found this an interesting writeup on the technologies needed to receive GPS signals: http://www.aholme.co.uk/GPS/Main.htm http://www.aholme.co.uk/GPS/Main.htm The combination of RF electronics and then doing the signal processing in an FPGA for the timing critical stuff and the actual DSP with a raspberry pi, very interesting.
