Hi,
I have a question regarding compass calibration, or any other calibration possible with Mavic Pro.

Manual says : Calibrate compass when flying in a new location or in a location that is different from  the most recent flight

The first flight I'm going to do is in Europe (France). The aircraft has been most likely assembled in China, therefore calibrated there.

So my question is : Is compass calibration necessary before doing 1st flight out of the box? (same questions for other kinds of calibrations)

Thanks.

As with all my previous DJI Phantom drones...  I would recommend calibrating the compass before each flight.  Just make sure there is not metal around when you calibrate the compass.

OK, thanks very much for your input, it's interesting to see the habits of users.
What about the other calibrations, what are your habits?

I still would like to know the official position of DJI team on this :-)

I think it would be a good idea to do the joystick calibration as well.

The IMU's probably don't need calibration unless the app reports an error.  However with a new drone I might calibrate the IMU's just to be safe.

Also make sure to install the latest firmware & DJI Go app.

OK, so you would recommend, for a brand new drone, to do all the calibrations before first flight. Noted thanks

I've read the opposite on these forums: Only calibrate the compass when the drone tells you to.

Given the conflicting information, I think waiting for (or finding) a DJI response is the best idea.

It's like all the other DJI drones.  You only need to calibrate when you get it, then again if you move a substantial distance from the initial calibration.  Calibration has to do with magnetic declination, something that changes based on your place on the map, or due to interference.  Calibrating every time before you fly is begging for a problem.

lol yup that's the statement i wrote in the opening post mate ;-)

What I wanted to know from an official DJI buddy, is if it does apply to the first use. If so, I'm happy to know it and it would be great if it was duly written in the manual, because people not wandering in the forum are going to start using the aircraft without calibrating it, and app isn't going to tell them to.

Of course you want to calibrate it out of the box. You don't know how it was handled while being shipped, through several carriers. Things could and will get out of calibration. Even if I lived a mile from the factory and picked it up at their door, I'd calibrate. If not for anything else it's for piece of mind. Something happens first flight, at least you'll know for sure it was calibrated correctly.

You may get differing views on when to calibrate compass first definitely calibrate before your first flight, and when you move any serious distance away, other than that you will be prompted when and if compass needs to be calibrated.
Yes out of the box do all other calibrations, it's also then you will learn how to do them, and you won't be going out flying wondering if they need doing, it doesn't take long and it will be very helpful going forward, good luck ...

That makes no sense. Calibrating often should never be asking for trouble. If you are calibrating you are setting it, so if you calibrate before every flight you are making sure you are absolutely up to date on your calibration. It might be unnecessary, but far from causing trouble.

Question.  How far do you think a "serious distance" is away from the current location?  Are we talking a few miles, or more like hundreds of miles?

Well I can only give you my experience, I regularly travel with my P4 30 to 40 miles I have never had to calibrate , or got warning to calibrate, a few times I have travel longer distance say hundred miles and further,, and although I didn't get warning or prompt to calibrate compass, I did it just to be sure, I have only once travelled oversea and again to be sure I did a compass calibration, I regularly check gimbal calibration and IMU, Hope this helps,

Yes thanks.  I have two homes that I want to use the Mavic at, one located in Calgary, Alberta and the other in Vancouver, BC.  These are about 1000 kms from each other and a couple of latitude values apart as well.  I would definitely recalibrate between those two, but perhaps sites within short driving of each place I might not need to.

There are other that swear by only calibrating it once and not mess with it anymore and that DJI is paranoid about this. People might calibrate on a bad location while already having a good calibration since last time. So, that might mess up a otherwise good flight.

My only experience is with the P2 and P3 which did not have dual compass & IMU systems.  My past experience reading the forum & my own flying experience lead me to calibrate frequently with the P3.

The Mavic is a different beast.  But I think calibration after is's been calibrated in China and then shipped elsewhere across the planet would lead me to want to recalibrate before the first flights.

Who knows what strange magnetic fields it gets exposed to while being shipped?  Xray machines, conveyor belt motors, Airplane electrical systems...  The odds of something getting magnatized in shipment is pretty good.

I would recalibrate.  Tha's just me.  Others can disagree.

Calibration won't mess up your flight so long as you carry it out correctly, refer to manual or check out tutorials, you may find a way that suits you , but it's important to know what is recommended in the manual.

Yes idd, calibrate when you receive it. That is whay I mean, but afterwards... I would not see why it would loose calibration. Unless it tells you to calibrate.

It will when you are in a bad location, unknowingly calibrating above a lot of metal in the ground for example. While last calibration was done somewhere open in a field. Then it might mess up the compass, that was otherwise still had a good calibration.

Yes I would calibrate the compass (correctly) before the first flight.
When I say correctly, that means no metal around the aircraft or under it.
Don't calibrate from a parking structure/boat/pier and so on.
And make sure no metal is on your person, key's, phone, jewelry, and set the RC/device about 10ft away on the ground then start the compass calibration.
IMU calibration, don't do that unless the app tells you to.

This is just me and I do not recommend it to anyone.
I barely calibrate the bird each flight unless the app asks for.
All I have to do is waiting for GREEN status saying SAFE TO FLY, then I start its engine and waiting for message Home-Point-Recorded before I take off.

Correct, the IMU and vision sensors should be calibrated if the app prompts you to.
And calibrate the compass again if the app prompts you too, and also if you attach or remove anything metal from the aircraft (like a GPS tracker).

Im sure this inst recommended at all. But is it possible to launch from a boat? If so. What are some tips to follow. Dont really plan on doing it very often. But living in Florida and boating quite a bit. Im sure there will be a time when Id like to do it if not to risky.

Doing it will not cause any detriment. I put it in "be safe rather than sorry" category. Given the product is produced in Asia (and I am in Canada - a considerable "relocation") I would do the works on arrival.

I do it and it's fine. Just do not calibrate anything on the boat. If you need to calibrate the compass, then do it on land with no metal around.
Make sure the boat is stopped and power up wait for GPS lock and go.
If you will then be taking the boat cruising after takeoff then make sure to set your RTH accordingly. You can se it to hover, or you can keep resetting the home point as the boat travels across the water.

I made a flippant reference to this in a different post; but when calibrating the compass do I need to go as far as removing my belt? How far away from metal objects such as cars do I need to be? And there are plenty of power lines and pylons about. When calibrating should I keep considerable distance, and when flying how close is too close?

Hi Ken, what will happen when boat is moving during take off?? Will Mavic automatically drift away because GPS will be trying to hold it in position or bottom sensors recognizes that ground is moving and Mavic will go with boat??

No problem at all, but I would stay on land for a few weeks until you are 100% confident in your abilities and know all the features, functions, and limitations.
Safe flying.

"if" is the key point here. The deal is, if there is something you routinely do, you will become sloppy.
If you calibrate when sense requires, you would diligently check for everything. If you calibrate before every flight, you will forget once that you carry a neodym magnet in your pocket...

The more often you do it, the more often you expose yourself to the risk of a bad calibration.  Things like cement parking lots, Car keys, electrical towers, etc, can all accidentally mess a calibration up.  Once you get a good one, the only reason you would need to change it would be if you moved to an area with a large difference in magnentic declination.
