The idea is to address the troubles at hand and nothing else.
That's a lot of maritime training though.

Without that level of training I could not run my business or as I often do - go out on assignments same as I send my guys out on.

I have respect from my guys through not asking anything I am not prepared to do.

As to address the troubles ? As I see it - there are none. You started this thread asking if there was a way to counter Compass error via take-off mat. Was answered - then degenerated into a slanging match that really is just not worthy of anyone here.

I watched a Ken Heron video where he takes off from a concrete and steel bridge in Tennessee near the TVA power plant. I wonder if he powered on his drone at home, put it in the car and hastily drove to the bridge to get around magnetic interference? I'll have to post that question to his video.

Mark ... I have a concrete standing in front of my house ... it has some rebar in it. I can ~70% of the time power up on it and no warning at all. But some days it just will not play there at all.

I ought to test to see if take-off is possible with warning ... and see if the generally accepted warning stops once risen away from influence. It will have to wait - weather forecast for this week is terrible.

Do you use the sticks to power it up or you take-off in atti mode?

If the cannot take-off due to compass interference doesn't allow me to take-off like I can with the Mavic 2 I take it seriously.

I'm lazy ... I tap the Auto Take-off on screen ...

Only if I am testing motors do I use the Stick to Start method.

ATTI mode ? Why ? I have a load of other multi's I can fly ATTI with .. I only fly ATTI with my P3P if keeping my hand in if needed.
It may be that when I test - that if it shows Compass Error - ATTI mode is only way to take off .. we'll see when weather improves.

When I need to Calibrate the P4 compass it won't let me take-off at all.

When you need to calibrate the compass?
You mean when your compass is warning you about a magnetic problem in the launch area.
Newsflash .. recalibrating the compass isn't going to fix the problem your compass is warning you about.

You don't need to recalibrate the compass.

I think he just typed quickly and meant when he gets warning ...

I'm not his defender ... just would like to see the 'levels of comms' reduce !!

I can take-off immediately with the Mavic 2 even with "Compass error".  I have to take-off on top of a boardwalk and of course, you can't really Move from that position due to the amount of people around.

I can't take off w/ the P4 at all but I haven't tried taking off in any other mode than P because someone said don't take off in A.  I got worried about a fly away.

A flyaway is juts a drone owner that lost his drone and doesn't understand why.
Drones don't fly away but some owners don't know how to fly properly.

You don't have to take-off from a boardwalk.
Launching from reinforced concrete surfaces is asking for trouble.
If your compass is warning you, best pay attention.

That's why I'm not taking off with the P4 over a boardwalk.  If it doesn't work in P, it doesn't work for a reason, but I need to see if it would work in Atti mode.  I never got around to doing it yet.

I need to have some sort of magnetic interference sensor.

Is this good?  I need to research which one is good.  The weird thing is when you get a "Compass error" when all the compass bars are below 3 digits.

Yes ... good idea.
It would come in handy when you know that your compass is intentionally giving you incorrect information.

AntDX316 Posted at 6-29 23:37
But it's not that out there compared to GPS unless they are trying to fly it in 3rd person.  Maybe they don't know how to fly at all and cannot RTH as a novice.

Huh?  This makes absolutely no sense at all.  Pretty much like everything else posted by AntHead-DX.

I know but it either says it needs to be calibrated or it's good to go.  I want to know what the readings of where it is are so I can make a correct determination of what is truly going on.

You need to get more reading practice to see what it actually says.

While it does mention calibration, that's one of DJI's well known documentation mistakes.
If your compass is warning you that you've put the drone down in an area where the local magnetic environment is unsuitable because some steel is too close to your drone, recalibrating the compass is never going to fix that problem.
Next time you see the message, take the time to read it properly and see what else it suggests, because that it the correct action.

ps  ..  DJI have given you the magnetic interference sensor you were asking for in post #92
They built on into your drone already.
See if you can find it

Compass Error/Magnetic Interference.  Calibration required.  Something like that of course.  Fix it, and it's Ready to Go.

OK .. how's recalibrating your compass going to fix the problem of your drone being too close to the magnetic field of some steel close by?

Labroides Posted at 7-3 21:15

These posts are incredible. This guys first post was about his compass not working, and after all the advice people have tried to offer, he is still talking about his compass. Ant, I think, your personal compass needs to be recalibrated and you should stay away from metal objects, it's affecting the way you think.

If you have warning of Compass Error / Magnetic interference :

DO NOT RE-CALIBRATE YOUR COMPASS - LEAVE IT ALONE AND MOVE TO LOCATION WITH NO ERROR

Where people mistakenly re-calibrate in the bad location - they then usually either 1. calibration fails to complete or 2. once they take off and fly out of the interference have Compass Error warning !

Well then go find a rough big open farm field well away from pylons, roads, metalwork etc ..... calibrate it there and then return to problem location where you want to fly ...

This kid must be mentally challenged or a true idiot.

He states the compass setting numbers are green on the sensor state settings page, which means good to go.
Yet he fails to understand that the blue calibrate compass link is just a link to the compass calibration page in settings.
He thinks it is telling him he needs to re-calibrate. Then when he does he see's the link is there and can't comprehend why.
He refuse to accept the information given to him by so many people here with more experience.

Ant you need to realize and comprehend...the blue calibrate compass link does not mean to calibrate the compass.

This is the problem with  these know it all personalities like Ant. They refuse to accept anything, unless it fits their way of thinking.

It says Compass needs to be recalibrated.
