Getting bad ground affect barometer readings

So I tried to auto land my quad today and it was almost a crash.

I am getting really bad barometer readings near the ground, when I got my Pixhawk I saw that it already had foam over the barometer, so I didn’t do anything special. I also have it mounted inside an AVDome. Any thoughts to make this better? I am seeing height swings of around 2M as I approach the ground so this wont work for auto land.

Any thoughts?


Hi kfennell,

Try lowering the LAND_SPEED

more information in:

It was already on 20, which is as low as it could go.
