Compass calibration - bad fit, using previous
#13
Photo 
Hi Guys, 

Im also getting a 'bad fit' compass calibration result.... and "using 1d fit"

....Although Im also still indoors (for now)
This thread suggested re-trying the calibration on the boat. Although I have a wood framed house, and imagine it shouldnt interfere. 

Heres my calibration view....
I see a circle of dots.....
but I dont yet inderstand the dots, dot colors, or pattern.

... and this is peculiar.... 
.... the headings response to a quick step (a step re-orientation of the IMU along the boat's 'flat' axis).....
The heading overshoots, then creeps slowly back down towards the original heading (resulting in a heading delta much less than the actual physical rotation applied).
It doesnt look good. 

(IMU is the IvenSense MPU-9250)
