Hi Fellow Mavicites,
I have noticed that many of our Pilots are having problems with the precision of the Compass/GPS combos with our Mavics. Often being the cause of annoying and frustrating flight inaccuracies, failing to follow commands, innacurate RTH's, loss of signal and highly likely to be a main cause in many reported cases of flyaways and crashes.
In my experience, although having not yet had my MP1 fly away, as others have complained, I have experienced some of the other problems. In particular the annoying failure to land on the spot with RTH, which was becoming worse with every second landing. (My Mavic would land up to ten feet away from the pad if I had not taken remedial action)
I found this so annoying and disappointing, especially as the little machine had been so accurate for the first 6 months of ownership.
I had regularly re-calibrated the compasses and IMU as per instructions and advice from the Members on these DJI Forums but never happy with the results.
I wondered if my actual method of calibration (and perhaps others as well) Could possibly have something to do with the inaccurate results we were getting!
Being from an Engineering and electronic background and an Inventive mind, I wondered if using a basic type of wooden turn-table (containing no metallic materials), to perform the calibrations would make any difference.
Well to cut a long story a bit shorter, I went ahead, designed and built a little prototype and "voila"-problem fixed.
Now my Mavic is back again to the precise landing and accurate handling machine as it was when new, I could not be happier now with its wonderful "spot on" accuracy.
Proves to me that the technique I (and obviously as many of you have found) this calibration thing is or can be, very sensitive and very important to perform correctly, for safety and preventing the possibility of an expensive loss of an unrecoverable flyaway.
Now I know others of you will dispute my findings, I won't argue with that, and whether or not these findings will be accepted is of course open to dispute. But I will say with complete confidence, that the difference made to my Mavic Pro, by using my rotating and tilting precise calibration turntable, has me convinced that this is a problem that can be fixed by using a device which is far more precise than the "human compass dance" we are instructed to follow in the manuals.
To be honest I don't see myself being able or interested in the actual production or sales of this very useful item, but could be persuaded to cooperate in design/ manufacture by anyone interested in running with it (for a reasonable commission or royalty etc...) What do you think?
Cheers,
