Today finally got Earth Bridge to work, giving a live feed to Google earth. Earth Bridge is a little bit dodgy, but after debugging with full error messages on Google Earth I was able to get it to work for me using these settings with Google Earth 6:
The weather was cloudy, so had a dodgy gps fix as you can see in the screenshot it appears I went mining before a jump with my laptop out into the paddock. When the system works, it is a great way to display the data though.
Next step to put this through the xBee and have a live stream from the plane!
