Attached are the logs for a flight today:
No GPS.
Arkflow Optical Flow (mounted 90 degrees clockwise on x axis, flow orientation is 900 in parameters).
Drone was launched in loiter mode about 30cm off the ground.
Drone hovered for a minute but yaw inconsistencies started to build up toward the end so I landed it. Tried it again and yaw inconsistencies varied from 170 degrees to 30 degrees.
Potential causes/concerns:
- Taking off in loiter mode and so close to the ground might not be a good enough position estimate and the yaw inconsistencies build up over time?
- Poor mounting of the Arkflow (vibration)?
*Magnetic interference?
