GUIDED_noGPS altitude

[sasoka (Sarath Asoka)]

Hi all,
I am working on non-GPS drone. For this, I’m using GUIDED_noGPS. I have a doubt on it.

1. Does the GUIDED_noGPS mode have automatic altitude control. That is, will the drone height change if the drone is moving over obstacles on ground ? From what I understand, we do not provide any altitude value like we do for ALT_HOLD, so that means no height control.
   If I give thrust = 0.5, the drone should not change height with or without obstacles, right?

Thank you.

In case it helps, a common misconception is that Guided_NoGPS should be used to control the vehicle in Non-GPS environments. This is partially true but the key difference between Guided mode and Guided_NoGPS is that in Guided_NoGPS the vehicle can only be controlled with the SET_ATTITUDE_TARGET mavlink message. If you’re looking to do Non-GPS navigation where the vehicle controls its position but does not have a GPS then you can use regular Guided mode but the vehicle must still have some sour…
