Satellite Count in Mission Planner – Which GNSS Constellations?

Hi all,

I’m using Mission Planner with my GNSS receiver, and I can see the total satellite count reported in the HUD and status tab.
My question is:

• The satellite count shown — is it the total combined from all GNSS constellations (GPS, GLONASS, Galileo, BeiDou, etc.)? Or only GPS?
• Is there a way in Mission Planner to view which satellites are being used from each constellation (e.g., a breakdown of GPS vs GLONASS vs Galileo)?
• If not directly in the UI, is there a MAVLink message or log entry that provides this information so it could be displayed?

I want to display the constellation-wise satellite usage inside Mission Planner for better debugging and testing.

Thanks in advance!
