1. I was watching this, then realized that it's actually not necessary for some GPS receivers. If you hook your GPS receiver up directly to a com port, then you can do a live feed into Google Earth. Check out the options under Tools>GPS. You can also import NMEA and other files there. These options are nice, since they automatically support more formats of NMEA data than just GPRMC.

  2. Great video and very helpful! I am setting up something very similar, and I was wondering if you could tell me how to modify the code a little. My receiver is already printing one nmea RMC sentence per second to the serial /usb port, so I just need to read the incoming strings and not interface with a device. I am also unclear as to how (and where) to set up the .txt file for python to write to. Any guidance would be most appreciated!
