Is barometer compensation and windspeed estimation working well, or are there any issues? I am working on this, but I am facing problems when the drone moves forward with increasing pitch. The drone starts loosing height and descends towards the ground. If anyone has any ideas, please let me know
As with all things ArduPilot related, it works well if configured correctly.

but sir i am facing issues related baro when the drone moves forward with increasing pitch. The drone starts loosing height and descends towards the ground .You have any idea to ressolve it?
Nobody can see how your drone is built and setup.
The baro reacts not only on static air pressure. Also dynamic air pressure by wind or by moving the baro through the air can have influence.
So first you have to isolate your baro as good as possible from these dynamic influences.
And you need to properly use ArduPilot methodic configurator software to correctly configure the vehicle
okay sir. I am using 4.5.3 firmware. I think I need to use latest version. Right sir?
No, you do not need to use the latest version.
But you should use the latest version.
And you must configure it correctly.
Notice my verb choices, in bold above.
sure sir ,where is your verb choices
need, should and must. On the post above
Hi @ramesh,
This sounds like the air pressure around the vehicle is changing as the attitude and speed of the vehicle changes. Normally the best solution is to try and adjust the frame instead of trying to change the software configuration (aka parameters).
This issue most commonly appears when the frame is designed with holes only on the bottom of the frame. For example if a large bucket like cover is put over the flight controller while the bottom is left somewhat open. It can also happen if there’s no cover at all over the autopilot.
Anyway, a physical solution where a balance of holes are added to the cover around the autopilot is normally best
That is the original question. That got answered correctly. AMC points to the windspeed estimation and barometer compensation, and explains, using an example, how to set the parameters to make them “working well”.
@rmackay9 The one you are answering is a different one, and more relevant: How can the altitude loss be fixed?
