Sometimes the drones are loosing the GPS signal that may end in a flyaway.But maybe when GPS is not available, or lost the position can be obtained by using Glonass? Or even upside down?

What do you think?

They already do it. Mavic's use GPS and GLONASS as their GNSS

But to they switch from gps to glonass if gps is failing?

Thats what my question is about.

They probably use standard receiver chips - they simply use both of them whichever has better signal.

Again:

My question is not does it use whats best when starting. Its: Will it switch from GPS to Glonass when GPS is failing?

I did not say about "using when starting".
All current GNSS chips continuousy use both systems.

Ok.

And all means in all drones or in "all systems using these chips"?

Who is to say it stared with gps it’s just as likely it started with glonass, I think you will not find more than 3 cases on this forum of loss of gps as it almost never happens very rare , yes it can be dropped in the case of data conflict.
