Hello,
I am working on installing an external GPS. I am looking for information about what data the Pixhawk needs from the external GPS. From reading how other external GPSs are integrated with Pixhawk, some are using NMEA messages. While it's supposed to be a convention it looks like vendors modify their NMEA message to suit their needs. Where can I find which NMEA messages can be read by the pixhawk and the exact sequence of the message? The plan is to use heading information from the GPS and not use a compass.
Been searching around for this data for a bit, but can't seem to find it.
Thank you,
David
