GPS 2 as primary GPS


I’ve a nice Septentrio RTK which is giving impressive results plugged into GPS2 of Pixhawk Cube.

Now I would to try to fly using the RTK as source for altitude and positionning.
How should I set the parameters if I want to use GPS2 as primary GPS such as I can fly using RTK data (also for vertical accuracy)?

I’ve some ideas for workaround but I would like to hear from you guys before.

Best regards,


It looks like it can be done by setting GPS_AUTO_SWITCH = 3. FYI - here is the wiki page on the GPS blending in case that helps.

Thank you, we did not see this new option!
