Hi Hanske.
Do you think that the transmission between the drone and transmitter could be affected, thinking in low level altitudes ?.  I remember you that here we don't have black boxes (Flight data recorder), so I guess, you guess and he guess......

The transmission frequency is too high for any normal solar activity to have any effect.  We are not transmitting through or off the upper atmosphere, our communications are purely line of sight.  

We would certainly loose the GPS long before since those signals do have to come from space through all layers of atmosphere but we never loose GPS, we just loose a little accuracy.

Poor Károly - he was entirely forgotton in this cosmic battle.

This is the answer to his 8m problem. Probably too late for him now:

"I don't accept your hypothesis unless you can show me confirming evidence to suport it."

Following your theory: Could you show me cofirming evidence that the solar storms doesn't affect drones activity ? ( GPS and Transmisions) Official reports with stadistics, please. Not your opinion, we already know your thinking

Reread post #33 above. where I already answered your question.

"I don't know where did you read that information, but 90% of reports involving drones in incidents with comercial aircrafts, are always in the vicinity of an airport."

Yes, airliners fly at 30-40 thousand feet, they pass 10,000 as they come in to land, over half the incidents "on approach to an airport" seem to be up around 10,000 feet.

Runway elevation in Heathrow is 82 feet, so 10.000 feet is a good altitud. Let's say that in an "standard" approach an aircraft at 10.000 feet, is about 35 miles far from the runway ( + or - ). When I said in the vicinity, I meant close to the final approach segment, about 4 miles far from the runway, at that distance the aircraft are at 1500 feet. And as I said before, most incidents are close to this altitud. Few weeks ago one incident was reported in Paris at 6000 feet and another in Barcelona at 4000 feet, but most of them use to occur below 1500 feet. At least in main airports in Spain, Portugal, Italy and France.

I'll try to make this clear enough for you.

If solar storms had the effects on Phantoms that you imagine, we would get thousands of flyers having trouble at times of high K-index.
But we don't.  It just isn't happening.
We have people like you squawking about the potential dangers but there is no evidence of any problems being caused.

Maybe you could provide some real evidence with statistics and official reports that show that there isn't a big problem with our drones being shot out of the air by aliens using energy weapons...

Agreed. There is too much needless hysteria generated by people with a small grasp of technology and radio communications.

Bullflyer, Labroides has nailed his colors to the mast, and he will never admit he is wrong, even if GPS is not affected, which it is , proved by his own statistics, in quiescent times at some places by as much as 30 metres of innacuracy, when a coronal mass ejection hits the earths magnetic field, the earths magnetic field rebounds, and the field lines that are normally stable move. This will affect the compass of both phones and ipads and any device you are using to make contact with the RC, and the drone itself. If geomagnetic storms can shut down a large percentage of power stations in canada in one incident, then it can certainly affect the electrical systems in a drone. But no matter what you say, Labroides thinks he is right, so let him think it. I have no intention to change his mind. Let him believe what he wants whether his is right or wrong, and we will leave it up to others to make up their own minds. As he said "Im no astronomer", so what he actually knows about coronal mass ejections can probably be written on the back of a postage stamp.

Spike ... you are 100% correct.
Almost all our Phantoms fall out of the sky uncontrollable whenever there's solar flare activity.
I just can't understand why no-one ever notices it when we are all up to our armpits in crashed Phantoms.

Hallmark, thanks, it's the irrefutable proof we needed. But maybe Dji let us see this photo, saying it was because of the solar storms ... and so we stop asking them why they fall, at the end these chinese are not fools, eh?

I don't want to get into this solar storm debate, I'd just like to add my experience with this same problem.  This has happened to me twice, both times it was at the same location taking off from a spot where I'd l eventually had 3 successful launches.  The first time it happened I could only go up 22 fee, the second it stopped me at 13 feet, both times I cycled the power on the drone and re calibrated the compass and was then able to take off.  I had at least 12 or 13 satellites online, there were no buildings around me only a few parked cars about 15 feet away and a light pole that wasn't turned on about 5 feet.  My max altitude is always set to 400 feet so I know that's not the problem, the drone was showing accurate altitude at the time so it knew how high it was.

You may want to start your own thread with this issue.
This here is the solar battle thread ;-)

And provide more info, esp. through uploading flight record(s) and sharing the links in your post:
http://www.phantomhelp.com/LogViewer/Upload/
If you are lucky enough that some of the specialists pick up on it you will be surprised on how much they can read from it.
Some will even be able to tell if you farted during take off ;-)

P.S.
Was the VPS activated on those flights?

Severe solar storm do have an affect on GPS accuracy as the plasma of the ionosphere gets bend and the calculation of the radio wave from the GPS gets inaccurate.

But we are talking about severe solar storms here, in level K 8 to 8 (the scale is logortimical).

It has been measured GPS inaccuracy up to 30 meter, during these events. Also the compass can be offset a few degrees.

This will not cause your drone to fly away, or fall down. But might mess up return to home landing a bit.

Anyway, storms in there katagories are rear. And and eruption on the sun takes three days to reach the earth.

Regarding RC communication. No I don't think I will matter at all. The radio communication are using long waves. With the high frequency remote and close proximity a few kilometers I do t think that aspect will matter at all.

Anyway the OP has got his answer solved.
And there are really no evident that solar storm has taken down a drone, even if it has a theoretical negative affect.

But to sum up, as a physician with studies in solar event... I would not fly in a k 8 index.
But then again I do not check as I see it as very unlikely

Whatever the KP index is, I never have any positioning problems with smartphone GPS or car navigation system.
This is certainly not different for the quad GPS.

May not be a problem if you are flying in manual control, but if you are flying a litchi mission , which is based on  pre set GPS coordinates for the flight, and you are flying close to obstacles, 30 metres of innacuracy could be a big problem.
