For me its just a belt and braces thing ...
I fly in different areas so re-calibrate when i get to a new area but I admit I dont always do it if I havent been anywhere different un less the app asks.
It's common for flyers to think that calibrating the compass is a safety thing (belt and braces) but recalibrating the compass is unnecessary and does nothing to make you any safer.

Ok so lets hope DJI just remove the feature all together as it seems a rather pointless part of the app if its not needed, if its only required once then it should be done at the factory and possibly after a firmware upgrade where they could just make it part of the upgrade process where users do not need to interact if say the settings on the sensors were wiped. Or just make it part of the IMU re-cal and make it a full system re-boot so to speak.

If I have been to say the US from the UK or UK to Hong Kong then I re-calibrate as I'm in a different part of the world but just driving down the road I wouldnt bother no.


Would also help if DJI didnt put it in their manuals too as its is confusing to all.

Geebax Posted at 6-30 17:02
"Can DJI confirm?"

No. The moderators on here are not engineers and in most cases, have no technical knowledge. And no again, it is not a procedure to set magnetic north. Read through the calibration procedure. Are you ever asked to point it towards north, or any other compass point?

I'm still unsure why the picture and the words are wrong on All the drones.  Point the nose down and turn 360 degrees but the picture shows it sideways..  How can this be missed on All the drones??  If I have it sideways, my Camera gimbal starts to overload and go crazy.

AntDX316 Posted at 6-30 15:51
So it's not really a procedure to set the actual position of magnetic north?  Can DJI confirm?

No it's not to set magnetic north and DJI won't confirm anything.

The feature is there for when you might need it.
That would be when you modify or repair your drone.
And no, it's not required after a firmware update, only when something about the magnetic characteristics of the drone might be changed.
Travel all the way to Hong Kong and it's not needed since it's not at all related to geographic location or magnetic deviation.

DJI documentation has quite a few inconsistencies and confusing errors.
The compass calibration thing is one of these.
They finally got it (almost) right for the P4 pro manual though.

More hearty laughs, from the peanut gallery, seating area... hahaha

I actually love it.

I didn't mean that, I have 6 years drone flying but that is irrelevant.  Where did you get your info for how the "Compass" actually works.

You don't even make your own drones as I did.  I have all kinds of RCs too from Boat, Nitro ground RCs, Heli, EDF aircraft, 90mph aircraft,  etc.

Years of experience does not always equal Scholar Archimedes knowledge.  I prefer tested and proven methods even if the knowledge was acquired as of 5 seconds ago in reality such as the mouse jumped 25 feet into the air from the ground with just it's feet but no one would ever believe it.

Grasshopper, I know it hard for you to understand but some people are more clever than even you.
Some know stuff from long experience and some can work things out.
Some even discuss with other clever people and that helps work things out even better.
Some people might not know everything but are clever enough to understand which people know things they don't and learn from them.
So far you don't seem to fit any of those categories.

You don't even make your own drones as I did.
You know this?  How?
Making drones doesn't seem to have given you much understanding.

Years of experience does not always equal Scholar Archimedes knowledge.  
I know.  I read something a minute ago that backs this up.

Try Googling the phrase 'swinging the compass', and you will get a good grounding in how compasses are calibrated in marine and aviation environments. In reading up on the methods, note that they know where magnetic north is located as part of the process. Then note that when you perform a compass 'calibration' on a DJI drone, that there is no requirement rto know where north is located.

I need to try it once when it asks for Compass calibration, to switch to Atti mode then give the findings here.

Everyone has to have some level of ignorance maintained; otherwise, it can lead them down the wrong paths when misunderstood.  As to keeping it managed while knowing is worth so much money.

AntDX316 Posted at 6-30 12:00
The real question is, does level-flight take calculations from the compass at all?

Be silly if it didn't ....

It's not altitude, it's the attitude to let the aircraft know if it's in level-flight or not.  Like, when you are off the sticks it stays in place.  Back then we had to calibrate the stuff ourselves and make adjustments but when the wind hits it, there is really nothing you can do.  That is what "attitude" mode pretty much is.

Like, when you let go, it will drift back left, forward, backward, diagonal, etc.  This happens when the aircraft cg isn't directly spot on in the middle.  It sucked messing w/ that stuff.  Then we went go FPV racer mode by putting a Gopro on it and flying.

?? Attitude Mode is purely without GPS or other external source of position data to assist in stable flight.

?? Aircraft CoG has nothing to do with drift ... drift is due to Flight Controller having inputs based on barometer / gyro / accelerometers vs air movement and its ability to not compensate quickly enough or that it compensates too much and gets into a to - fro motion.  CoG is compensated by differential use of the rotors, a function the Flight Controller is designed for with all the rest it does.

The calibration if done requires all axis to be checked. That means to complete two turn-abouts, first with drone horizontal .. second tipped vertical. Why both ? Magnetic flux is a 3 dimensional force.
I have never had gimbal / camera complain in this ...

It would be so much better if the thread was not infected with insults ........ it could be entertaining instead of embarrassing.

Hauhgtiness comes before the free fall. But this joke by side: Nigel is right. It´s 3-dimensional. Some animals have sutch biological compass and react of the magnetic refraction in some areas.

Can anyone tell me where the magnetic Northpole is ? and why the compass needle is alligned to the North - South - Line??

" I'm just trying to understand things of how they are, not because of how people were taught to see them. "

Here is the issue. You seem to be under the impression that those of us out here fall into the second category of people. those who were "taught to see them" a certain way. And at the same time, you think that because you make a first person observation that is different, that you are right, and they are wrong.

Being taught to see things a certain way ignores the fact that those people may have been very well schooled and educated in the sciences and possibly specialising in these fields, and you put yourself above them in terms of quantum of knowledge.

The net result is that eventually they will ignore you, leaving you no wiser than when you first came here. It has been often said that the best way to gain knowledge is to shut up and listen.

Shutting up and listening to the wrong people is how to do it wrong for those who will venture Beyond what you and people like you have taught them.  I prefer Military-grade intelligence, not civilian-grade.  Civilian-grade is fine.  The laws of physics are the only law to abide by.  If anything goes wrong trying to complete things far beyond the civilian level and die doing it, take out others in the process as well, it's ok because this is what you teach.  The teaching is incomplete, in my opinion.  Anyone who is doing things beyond the norm, and gets screwed for doing it, you and everyone else will move on who is not involved.

I'm the type that does triple digits Easy on the Sportbike.  I'm the type that rides coasters all day for days.  I'm the type that goes far into the ocean where no one is there but sharks.  I'm the type that has driven 18-wheelers across the country, flown aircraft, worked out with very heavy weights despite my size, and I'm still here w/o issues.  I've also done a lot of other crazy things that I have survived doing.  If you and people like you want to dismiss me, you are very, very much mistaken but I will leave it as that.  I've already determined so many times how people won't believe me because I don't have this, I don't have that, they don't see this, they don't see that, it's a waste of time.  Some people ignore, some people stay at their level, etc.  I choose to involve in All areas, but as anyone who can see everything knows, that is unwise.  It's data gathering for me.  This way, I can truly understand where the ignorance is and how to work w/ it or on it for the greater good.

People like to stay with their belief system.  Some systems are flawed and need work.  At times, I need work, but some areas people would die/have died doing Half of what I do and have done even though it may look like I know nothing if the circumstances are presented improperly.

Keeping things to ourselves is the most efficient way to go about life but comparing is where we can dilute and separate who is most correct and who isn't no matter How good it looks.  Without running certain tests and evaluating the results, anything is good!

I pretty much wander life with the same attitude most of the time, and I've noticed it's all down to what is happening at the moment.  What is happening at the moment, with the same attitude, can mean the difference between 100x effect and -100x effect.

Being shy before was great.  Not knowing how dumb people are was truly peaceful.

I am often in conflict with some here, but thats accepted and all part of the forum life. I may not like some replies but again - that's forum life.

I have a lot of years behind me ... done many things that my Sons and others who know me reckon I should write a book about. But I am still learning and will be till my last breath.

I noticed your early posts before you changed ID ... were very 'beginner' content. But within a couple of threads - you were then posting as what appeared a 'Commercial Operator'.

Sorry 'ant' but you need to step back a bit and not 'fuel' the replies you are now getting. Putting it bluntly - you are arguing with those that 'enjoy' the fight and they will grind you down - take my word for it.

On the matter of Military vs Civilian ? You have to be joking surely ? I am a Civilian Business that often works with Military and I personally have gone into War / conflict locations that many people would not dare to.  One of the conditions I insist on before I or any of my guys proceeds - is the choice of who 'guards us' ... you can have 3 guesses who it is NOT !!

Why the CV ? Do you honestly think they define intelligence ? Not so long ago Trump tried the same by challenging the Mayor of London to IQ test comparison. Anyone with REAL intelligence knows that's BS.

Just for the record - basically because you think it important :

I hold :

Driving Licence that includes commercial trucks
Senior Ships Deck / Navigation Officer Licences in 4 different National Authorities
Radar Operators and maintenance
Electronic Navigation Systems Operations
All class Pleasure Boat licence (Ocean Sail /  Power and Coastal / Inland waters)
Multiple Safety Course Completion Certificates for Petrochemical facilities and shipping
Ship Captains Medical Certificate
Basic and Advanced Maritime Fire Fighting Certificates as endorsed as In Charge.
Dangerous cargo Endorsements including In Charge for cleaning / cargo transfers / carriage.

I could carry on as I have a whole stack more of them for my work ... but my point is - they do not make me more intelligent than others.
