I am guessing, the EKF is seeing a conflict between GPS, Airspeed and perhaps accelerator.
If this is the case how would one go about resolving such a conflict?

I had a quick question around mounting a LiDAR on a stabilised platform on a drone to counteract the pitch/tilt of the airframe. I was thinking about a steward platform with some servos however I'm using something like this below and it alre

I want to use an RTK GPS (likely this one: http://www.drotek.com/shop/en/home/762-l1-rtk-gnss.html) for aerial mapping in high accuracy.
I think there will be a deviation in the geotagging as the Photos might be taken not exactly at a GPS-inp

In chart above I try to roll the plane to right (RCIN red lines), but it doesn't react (RCOUT green and blue lines).
