IMU Error

koffe · Jun 10, 2018

I have run Autopilot a while ago. Today it was impossible as there was IMU error. Loaded GO4 and calibrated the IMU as well as the compass. Then it was OK here but after shutting down everything and started Autopilot again there still was IMU error…?!?

What can I do more?

Seems like a reboot of RC and AC helped. Like so many other times with so many other items....

I did not recalibrate but went into djiGo4 app and confirmed my IMU and compass both was ok
I restarted both the AC and RC and restarted the ipad - IMU error still was present
Any suggestions

Go to Airdata.com register an account (free) upload your latest flight and check for warnings and faults. I did that but only after that my Spark had flown away and never was found again. I have written about that in another thread.

And I found that I had many faults that escalated over time. I do think that there was a bad connection between sensors and motherboard. That is the only analyze I can do. But what do I know...

Now I have bought another Spark and start with checking every new flight in the beginning with and with the first two flights there were no faults.

I suggest you check that before and not after as I did. Beware.

but tht still did not resolve the Q on how to correct the IMU error in Autopilot
Do you stilll use autopilot with new spark ?

I have just run 3 short tests with AP and so far it looked good. For me, I still think that there could be some truth in bad connections as I had the same fault as you describe. Did you check with Airdata as sggested? What result did you get?
