Hey guys,
which one is the best altitude message to subscribe to if I want to get the altitude between ground and drone?
I know that there are many altitude messages to subscribe to e.g.:
- global_position/rel_alt
- global_position/global
- local_position/pose
- altitude
At the moment I am using the local_position/pose altitude and have noticed that this altitude is not very good. Even when I start the drone on the ground the altitude is at 2m.
Does anyone has a hint which altitude message would be best to use?
