"real-time GPS-driven moving map display"Not the IMHO more interesting analog tech which lifts signals out of thermal noise.
I found this an interesting writeup on the technologies needed to receive GPS signals:<a href="http://www.aholme.co.uk/GPS/Main.htm" rel="nofollow">http://www.aholme.co.uk/GPS/Main.htmThe 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.
