Problem for the positionning

#1

Hi everyone !

I have a problem for the positionning of my drone.

For a better understanding of the problem, you will find attached a diagram.

My drone take off at the top of a mound.

Its point of arrival is 30 meters below.

At first, it would be quite possible to program the drone so that it has GPS point with an altitude of 20 meters, then it lands to the GPS point (green line on the diagram).

But the altitude is too high.

The second idea would be the Red line on the diagram. But, when I see the FlytAPI, the rel_alt_z must be positive (:rel_alt_z: Altitue (Positive distance upwards from home position)). In my situation, the altitude must be negative ( -23meter)

Have you a solution for this porblem ?

Best regard,

Raph

Hi Mr_Snicker5
The rel_alt_z will depend on the Frame in which the waypoints are given.
Use the Global frame to give negative altitude to go in a downward direction.
Also, you have to adjust your Waypoints as per your location.
