Altitude Hold Problem - Barometer issue?

Posted by charliedeets on June 30, 2014 at 10:57pm

Below is a graph of my X8 with APM 2.6 sitting on the floor next to my computer. As you can see, it thinks its slowly rising. When I am in Alt Hold or Loiter, it rises slowing in the air.

I'm trying to understand what is causing this. Could it be the barometer built into the APM? It appears that the reported pressure is directly associated with the Relative Altitude. If so, is there any fix for this, or is this a hardware failure?

Mine does the same thing but when i did some research into this I that this is normal. I find once it warms up and i am flying around it is ok.

  Ok thanks. I was under the impression these modes would be more accurate than this, but maybe I'll just invest in sonar.
