but why the gently caress are you defending a rich person by poking holes in a story making fun of someone who is rich?

it is fascinating how you think calling out an obvious lie based around having a friend at some weird arctic tourist base is "defending the rich".

like sagebrush got a history on these weird little stories that are obviously fake, like when he claimed there was an "african tribe" that punishes murderers by holding them in solitary in "the tents" and then have a ceremony where the murderer is rowed out in a lake and if the victim's family rescues the person from the middle of the lake the "tribe" treats it as if the murder never happened because ~forgiveness~

i just don't see how this results in a drone not being able to navigate, unless the thing the operator wanted it to do was specifically follow a magnetic heading.

like i doubt the cheapy ones with a glorified rc car controller care about a compass direction, you steer them basically all manually and even the very fancy ones still have that usually. and you're usually expected to keep the thing in visual range to handle that, or you're going to be putting on a camera that can be used for flying visually.

plus the ones fancy enough to have gps nav should be able to move between gps waypoints absent the magnetic compass even if it'll be less reliable than if you're sitting at the magnetic equator and can expect the most reliable compass response.

ok so to be clear your argument is "here are a few ways that i think drones should work, q.e.d." but you don't actually know how they work, nor have you presented any evidence that they do work like you suggest.

imagine that the drone has some simplistic navigation logic that uses the current gps position to calculate the bearing to the next waypoint, turns the drone to face that bearing using the compass, and flies forwards. what happens to the drone if the software doesn't account for magnetic declination? what happens if the declination at your location is 50+ degrees?

that story was told to me by a friend years ago and i repeated it here without bothering to verify it. after getting called out, i dug around and it turned out to be an anecdote written for the nicole kidman movie the interpreter. i've been earnest about that on a number of occasions, you can dig through my post history if you want

no, it's that GPS absolutely does not have anything to do with magnetism, and the magnetic poles/high declination do not prevent GPS navigation from working. this is how it is known that your story is bs.

but within your boneheaded theory, you have the mere amount of declination being enough to defeat using a compass. this is false, declination tables are widely published and even something a few years out of date won't radically break your navigation. you have the gps to tell you where the device is and lookup proper declination. it doesn't mean your compass is gonna spin around wildly or any such nonsense.

a UAV uses a combination of gps (absolute position), inertial references (dynamic orientation), and magnetic sensors (absolute orientation) to navigate in three-dimensional space. when one third of that data is wrong or unreliable, navigation suffers.

your new argument, based on your recent searches for "what is magnetic declination" and "how do drones work" (look at those goalposts fly!) is that obviously the drone manufacturers would have accommodated in their software for extreme cases such as operation close to the magnetic poles because it's so obvious therefore none of these coders could be lazy or cheap. even you know better than that.

incidentally, gps itself also breaks down in the arctic for reasons unrelated to magnetic declination: https://www.allaboutcircuits.com/news/navigating-the-arctic-why-gps-might-fail-you/

gps works fine in the arctic, the arctic is in fact one of the most critical places for it to work due to its invention as a tool for the military to use. there is minorly reduced reliability compared to the middle latitudes but that's not going to make a drone crash that wasn't already going to crash in cleveland

compasses aren't wrong or unreliable at high declination, they're simply troublesome to use over very long distances without re-adjustment.


your story was made up just like the racist africa story and you are flailing to defend it just like you flailed to defend that.

"Hi Sir,

Thanks for your patience.

For your claimed case CAS-xxxxxx-xxxxx, we have already finished the analysis, and the result is as follows:
Flight time:2016.09.01 09.22:51(utc+8)
FLY022; Home point:74.7215634, -91.8416966; Last point:74.7154911 -91.7417518;
1.The aircraft was controlled by pilot in gps mode;
2.T=17:26,h=-9m,d=3018.5m,flight record interrupt during Landing by intelligent battery;
3.Compass navigation bias was too large, the aircraft lost control due to environment.The Phantom 4 cannot operate within the polar areas.

According to the analysis, the incident was not caused by any product malfunction factors. As such, we could not provide warranty service.

Should you have more questions, please feel free to let me know.

It's kinda silly but they aren't actually automatic, a couple guys in trucks hang out at the entrance before change over and switch it manually then drive through stopping at each on ramp to switch it over and make sure there are no stalled cars still pointing the wrong way. The gates have some relay interlocks and I think are networked to the control center in shoreline but there are safety vehicle arrest nets that need to be removed by hand. I know all this because I had the misfortune as part of my job to follow them through and cover up graffiti while they changed over. I still have nightmares about discarded dope needles from that job.
