General Discussion / External antenna for GPS Shield

« on: November 11, 2014, 07:21:32 PM »

Anyone tried to attach an external antenna to the GPS shield? It would be nice to have an external antenna for better reception. I've got a couple of magnetic mount Garmin GPS antennas and wonder if they could be used with the shield.


Thanks.

Your file has no location data. If you look at the text file, the $GPGGA line is the location sentence. The first item is the time of the fix (190413.838 for your first one, this is 19:03:13 UTC), the following comma separated elements should be the latitude, longitude, then other data. Yours are all blank - nothing between the commas. Your GPS must not have had a fix.

Check out : http://www.gpsinformation.org/dale/nmea.htm for what all the lines and data elements should represent.
