Hi,
Currently trying to set up a locuste quad, and going through all compass calibrations.
In order to avoid interference, I have positioned my UBLOX GPS+compass at the very back of the quad, and up by let’s say 10cm. It seems to me like this position should be fine in terms of interference.
However, I’m getting 48% compassmot in this configuration. Also, when calibrating the compass (method described by Chris A. in one of the videos), I still get some huge values for the compass offsets - some values are within -400 +400 boundaries, but one of them, sometimes 2, are huge numbers…
When setting this huge offset to 0 (to be able to arm) and loitering, then of course I get the “toilet bowl”, which I guess is logical with such problems…
I’m out of idea, I have tried to move the compass/GPS to the front, still up by 10cm, and it’s giving me the same results after calibration. I could raise it more, but I suspect the problem is elsewhere. Even the compass sitting on the APM will give me the same results
Can anyone think about any reason why I’m getting so much interference, and why I can’t properly calibrate the compass (offsets) ? would my big motors be responsible for this big magnetic interference (when running compassmot at 50% throttle) ?
