anyone out there watching the poles moving. I found it a fascinating subject since I did a tech paper in college.
politics aside, I've been trying to "see" how earth low atmosphere weather is effected by magnetic fields. My simpleton idea is earth weather is a + - electrical thing, then introduce a magnetic field and you wind up trying to do the M(motion) F(flux lines) C(current flow -( weather)) thing, I always forget whether it's the left hand rule, or right :think1:

I am watching what they are finding under the ice in Antarctica :)

Driving in today and noticing the early morning spraying in the skies, I wondered, is all that aluminum beginning to short the field at this point? Or is it the, Augie kootu indouie baku- Nibiru that cometh?

I drove back from FL early March, somewhere Northern GA, and my GPS "bird" started drifting bad, got almost 2 miles off course, got all manner of confused, me, I was just laughin, yelling at the GPS to just look at the stars!! :icon_biggrin:
-
The magnetic poles are moving so fast, they have to update the GPS systems way more often
-
Yup, and mines an obsoleted Garmin from the late '90s!! I like it for the shear random confusion it has over new interchanges, stores no longer "there".... :icon_biggrin:

You can't download new map data?
Most Garmin's are able to do that
Someone gave me an ancient TomTom
I hooked it up to my PC and it updated
So I would think a Garmin could do that also?
I used my Samsung Tablet as my GPS on my last trip to Michigan
I have a holder for it
It's bigger than most in dash GPS screens
Just use the open street maps app
Download the off line state maps you need
They get updated once a month
It uses the GPS in your device and it is great and free
-
It might upload, when the gps boots up, it tells me to contact Garmin, I believe I did 10yrs ago, IIRC, I was told to ship it and pay. :dontknow:
so far I've never been lost enough it wouldn't get me back :icon_biggrin:
-
Yeah but what about Yellowstone
silverfox.

:l2:
I had the family there 15yrs ago, my Step Son an I were getting testy and I'd already been there 2 times, so I had my wife drop me at the North end of the "circle" tourist loop. I showed her where I'd meet them and set off with a day pack and old skool compass. south 2 miles, west 2 miles, road......NOT. :cussing:
Above the canopy as I was traversing West was a High tension power line, it kept dragging me NW, I knew enough about back country navigation to know something was wrong! about 2 miles later I came to a giant sub-station in the middle of no-where :think1: There was an access road I hiked out about 2 miles from my destination :BangHead:
-
GPS does not use or reference magnetic north? Ships and planes use magnetic compasses as a backup so charts and runways need regular updating.
Yeah, Shooter went wandering in the woods of Yellowstone one day and disappeared. Found his body in British Columbia for some reason....

GPS gets it's data from satellites by triangulating your position
It's not all that accurate unless you have at least 3 satellites far apart and closest to the horizon
3 satellites directly overhead has a big + or - guess
It's normally about 25 to 50 ft + Or - here in the mountains

Right. So GPS updates (Garman, TomTom, etc.) would be for road and feature updates, not because the poles are moving. Shooter may have been down to 3 when his started drifting, again, nothing to do with the poles. Orbits and obstructions. My drone references GPS too and will not reliably do (or guarantee) an auto return when out of range or signal loss without, I think, 4 or 5 sats I cant remember. Amazing stuff. Science fiction not so long ago!

Yes, the GPS updates are for the base maps inside the units
And operating system updates
I don't know how in dash car GPS units do it
I am talking about my hand held Garmin Oregon trail GPS

Found his body in British Columbia
Roflmao! :l2:
BC is another story!!! They got some REALLY big Bears, I stayed close to the car there :icon_biggrin:
Aside;
Sad story in Yellowstone;
when I was "lost", came across a "sand dune" kinda place, 100's of yards in diameter, after clearing a swampy area, as I got closer, I had an unexplainable "sense of despair", then I realized why, in the sand were hundreds of large bones, weather worn, the closer I got the worse I felt, what I had found were the dump grounds for all the bear that had become "tame" from moronic humans tourists of decades past!, I prayed and cried.......A day and Moment forever with me.
-
I should have said "Found his body in British Columbia under some power lines with compass still clutched firmly in his hand." :l2:
Bears/Idiot people :violent1:

This was what I was referring to.

there is some governing body, (military?, civilian?, alien?) that does the wizzbang math and comes up with ahSHEET, um, we gotta update the global system :think1: pretty sure whoever they are couldn't pull a factory 8hr shift then a mandatory 12 hr OT, so they got into GPS systems :icon_biggrin:
