Have you ever thought about designing a GPS Receiver? It seems very complicated but not with this design we found at holmea.demon.co.uk, the article clearly explains how to make a homemade GPS receiver and we thought you guys would find it very useful.
“…I was motivated to design this receiver after reading the work of Matjaž Vidmar, S53MV, who developed a GPS receiver from scratch, using mainly discrete components, over 20 years ago. His use of DSP following a hard-limiting IF and 1-bit ADC interested me. The receiver described here works on the same principle. Its 1-bit ADC is the 6-pin IC near the pin headers, an LVDS-output comparator. Hidden under noise but not obliterated in the bi-level quantised mush that emerges are signals from every satellite in view.”
The article is complete with source code, resources and more so that you can start making your own GPS Receiver!
