I stumbled over this article about a lost drone in the UK. https://www.forbes.com/sites/davidhambling/2020/08/10/investigation-finds-gps-interference-caused-uk-survey-drone-crash/ It’s states that the crash was due to gps interference and that’s why the drone was drifting but isn’t this a...

Thanks, good to know! :)

Awesome read, thanks! So there’s really no reason to perform compass calibrations ever now and then “just because”? I mean, if all the values look good and the aircraft position corresponds with the compass arrow, everything is okay I guess? Even if the takeoff location is a far way from home...

I had similar issues with exactly the same errors and in my case it appears to be caused by a magnetically interfered calibration site. As soon as I took it to another place which was further away from any possible objects that could interfere and re-calibrated, the errors was gone. Have been...

Do you know it is possible in terms of hardware of having the same detection/correction on the MP as well? It would sure feel a lot safer to have that function since it's hard to tell if there's any magnetic interference nearby or not. If possible, then maybe we can hope for a FW update on the...

The strange thing here though is that I kept getting this error in multiple locations no matter what I did but since calibrating the IMU and compass I haven't seen any errors at all when flying in the exact same locations. I'm glad that the problem seems to have gone away but on the other hand I...

Just a little update here. :) I did an IMU calibration and I think that it might have solved my problems. No more errors (no more compass/IMU/yaw errors) in the logs since and I've done a couple of flights in different locations and so far so good. Fingers crossed!

Thanks, I edited my post with your link instead since airdata messed up the whole page layout for some reason. I guess I won't be able to figure out the exact reason why i got these compass errors but I'll just have to believe that it was due to "dirty compass" location. I have tried to look at...

Here is another flight from the same location (same day) that I have uploaded: https://www.phantomhelp.com/LogViewer/3MLBZFTXYXF1Y5ENJU2F/ As you can see, here is also the yaw-error that i was talking about. Do you see anything worrying about this log or is it just because of a bad location...

Thanks for the explanation! So these errors shouldn’t pop up mid flight really in normal conditions unless you are flying straight above something that could interfere? In my case, would it be a good idea to re-calibrate both IMU and Compass in a new location prior to my normal start location at...

So if I see this message briefly when flying over something I shouldn’t be too worried about it as long I’m not launching from a magnetically interfered area? I went through some logs from a flight out in the open fields with no structures within miles and I only have a few compass errors in...

Ah I see. I actually launched from a wood table with a steel-frame and nearby there is a big frame for a big outdoor roofing structure for a dance course. The errors is indeed occurring close to the launch location. Didn’t know that steel had so much impact on the compass but maybe that’s the...

Ok thank you! I have uploaded the flight data for that specific flight on these links: https://www.dropbox.com/s/adg7utvg1hex6vj/DJIFlightRecord_2019-09-08_%5B15-51-00%5D.csv?dl=0 https://www.dropbox.com/s/5vu104ka8u3eojp/2019-09-08%2015_51_04-08RDF9NP010336.dat?dl=0...

Thanks, good to know! It was steady before re-doing it so apparently it was unnecessary but I just wanted to be sure that there was no problem with the compass. So, the gps error that i saw has nothing to do with the compass calibration? Edit: Is IMU calibration something you need to do after...

Hi all! New guy from Sweden here that's just started flying! Happy to find his forum, seems to be a lot of good expertise in here and i feel like I could spend many hours of just reading old threads ? And that brings me to my question. I have read a lot of crash-threads (i don't know why since...
