Takeoff no gps ?

is it possible to make the tkoff function work without gps?

Yes. Just takeoff in stabalize flight mode.

I need the takeoff mode to work without GPS. I can take off in manu. the task is different.

If you can takeoff in manual mode, do it. It will work without GPS.

If you want to takeoff automatically you will need GPS.

and if there will be gps, but satellites will not catch it? is it possible to do something? set it up so that he does not pay attention to the number of satellites? thanks

there is a compass on boar

It does not matter if there is a compass on board. It requires a good quality GPS signal with a fixed, valid GPS solution.
