Have flown Mavic Pro and Phantom 3 in Arctic regions (Siberia and northern Norway, north of 70N). The compass and limited GPS/GLONASS coverage issue is indeed a problem. Just expect that the drone switches to ATTI in midair. Under strong wind this is not pleasant. I also noted, that the errors...

Sure, it will fly. Just be careful in case it looses compass and/or GPS and you will have to manually fly it back.

Was flying at 69.5N. And last September also at the same latitude but in North-eastern Siberia on the Arctic sea coast. But I think it's the geomagnetic latitude that matters. For that you are in Canada worse off. I also noted a clear correlation with solar activity: The errors were much more...

They actually have very reasonable rules in Finland: Check out Droneinfo - Main.

Compass calibration is especially needed when flying in high latitudes. Had big problems in northern Finland and in northern Siberia at latitudes higher than 67°N. Also when solar activity is high, the magnetic field gets more distorted than elsewhere; hence daily calibration is highly...

Are you living in high latitudes? Alaska? Had similar problems when flying in northern Finland and in Arctic Russia. North of 65N, depending on the solar activity it gets tricky...

Fantastic location and great shots - congratulations!

Great scenery! Where in the world is this?

There are many different definitions of "polar regions". North of 60N? North of 65N? or north of 70N? And why is this restriction? There are lot's of GPS and GLONASS satellites in sight at high latitudes.

According to the Mavic Manual, flights in P-mode in "polar areas" are not possible (page 50). I was flying in northern Finland and experienced quite frequent drops from GPS to Atti mode in mid flight, and GPS was not recovered for 1-2 minutes - quite scary. Analysing the log files, I noticed GPS...

Anybody got this message? What does it mean? The full message on Healthy Drones reads: "Warning:[IMU]heading exception (In Flight) please switch to atti mode if craft behave abnormally" Was flying in cold weather (-10C) at a very high geographical latitude (Northernmost Finland, 69.37N). Not...

Sorry - was not intended:)

I agree with that. But this interference, since it is not directed, should decay with 1 over the third power of the distance. If the parabolic satellite dish were used as a emitter (such as in radio communication), it would create a beam in which the intensity is only decreasing linearly with...

It is hard to believe that a normal TV satellite dish causes interference. After all, the dish is only a receiver and does not send out any signal. Thus there is no "beam".
