We have fine-tuned a DJI S1000 with Pixhawk 2.1.
It works well, except when we fly in AUTO mode with the “Terrain” Parameter setup in the mission.
In this case Pitch and Roll start oscillating significantly and the altitude changes periodically (as we see from the Rangefinder measurement - it is a Lidar SF20 I2C version); motors seem to work erratically.
If the same mission is flown with “Relative” instead of “Terrain” then the mission is performed quite well.
It happens every time we set “Terrain” instead of “Relative”.
