Hi all,
How do I determine when is it relevant to calibrate my AQ board with DIMU upgrade?
I installed my board with DIMU upgrade on my quadcopter. After executing TARE and storing the values I'm able to fly around. Position hold works fine, even in strong winds. Altitude hold works reasonable, but I experience slow upward drift. I was not able to correct this drift with PID adjustment.
So I put my quadcopter on the dining table and connected to mission planner. When I look at my acc-x, acc-y and acc-z values I see them drift (with the rising temperature of the IMU).
For example my acc-z drifts from 9.2 to 9.6, with rising temperature of the IMU.
- What effect does this have on altitude hold? My acc-z values are way off from the ideal 9,806 m/s2.
- What values can be expected? Can anyone with the DIMU upgrade post their values?
Best regards,
