TechMinds: Decoding GPS with an RTL-SDR
Over on his YouTube channel Tech Minds has uploaded a video showing how it's possible to receive and decode GPS signals with an RTL-SDR. To do this he uses one of our RTL-SDR Blog V3 dongles and a GPS patch antenna which is powered via the bias tee on the dongle.
On the software side he uses GNSS-SDRLIB and RTKLIB to decode the GPS signal. The result of the two programs is your current GPS coordinates which can be plotted on a map. Unfortunately in the video Tech Minds was unable to get the Google Maps display to work, but you can easily type the coordinates into Google maps yourself.

Any idea what would cause one or some of the blank pop-up cmd prompts to get stuck on start? I think I have a decent signal but always hangs on launch so it seems like a Windows issue but not sure, If anyone has any recommendations or experience it would be appreciated
