Hi,
I have an APM 2.5 on a hexacopter frame and I am getting background noise on the gyros as seen looking at the tuning raw sensors on the mission planner.
The noise on the gyros when the platform is stable on a desk is enough to cause the camera mount servos to continually jitter. The movements are big enough to cause concern for the video quality when airborne.
Is there any way to isolate/filter some of this.? I re-tuned the accelerometers with the main battery plugged in just in case there was a need to cancel out any electro-magnetic interfernece from power modules/ESC etc (although know that I think about it, the ESC are not armed when accel is tuned, probably it doens't matter as the jitter persists in any case).
Any ideas, I heard there was a filter library, is this not compiled by default?
I am trying to get a prof setup going and if I get to the bottom of this it would HELP a LOT!!
Thanks

If I remember right, someone mentioned that this is typical of a pre-armed response, ie noise/jittering reduces once the copter is armed.
In my case this was predominantly cause by a bad setup of the potentiometers that controlled the stabilisation servos on my AV200, (still no happy with it).
I think going the brushless gimbal stabilisation path is the only true solution for these kind of problems. I am currently waiting for the CNC cut aluminium parts of my design setup to test stabilisation using brushless motors.
I too have this. As, I'm sure most people do. I would love to know if there is a fix.
