pitch and roll small variation when gps is 3D Fix

Posted by Sergio Beltran on May 17, 2013 at 9:51pm

HI, i am testing and octocopter with APM2.5. In this moment I am tunning stabilization mode. after several flight i notice small variations in pitch an roll when the arducopter is on ground. I discover that this happens when gps is in 3d mode .

GPS STATUS 1: pitch and roll variations +/- 0.03
GPS STATUS 3: pitch and roll variations +/- 0.4

can someone give me explication about this behavior, it's normal?

Thanks

Here's a description of this on the Trouble shooting page here including a video. We use the gps for centrifugal force compensation. From AC 3.0 we will disable this while the copter is disarmed so you won't notice it anymore.
