"real-time GPS-driven moving map display"
Not the IMHO more interesting analog tech which lifts signals out of thermal noise.
- JPLeRouzic 18d agoThat looks interesting, what technology "lifts signals out of thermal noise"?

- y04nn 18d agoDSSS, direct sequence spread spectrum, used for encoding GPS signal
- peaseagee 18d agoSpread spectrum, it's pretty magical.
- JPLeRouzic 18d agoThanks @FrankPetrilli.
- squantor 18d 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.
