I'm outputting NMEA strings via Mission Planner with my Plane hooked up to a secondary RTK GPS. I'm getting funny altitude number coming out in the NMEA so I'm wondering what is the origin of the strings. Are they from GPS 1? GPS 2? Is the altitude reported based on the barometer or GPS 1, GPS2 or combination? My altitude seems to be off by around 600ft, so its not a HAE/MSL issue.
