Garmin 430/530 up north?

[CaptainCraig]

Hi,

Has anyone had the opportunity to use a Garmin 430/530 north of the
60th parallel?

I'm talking Inuvik, Rankin Inlet, Iqualuit...

I am not finding anything in the Garmin manual and I know that
satellite coverage is questionable, I am just wondering how it would
affect day-to-day operations.

Thanks!
Craig

The entire planet is covered by GPS. However, satellite orbits are optimized
for middle latitudes, so accuracy is slightly less at extremely high
latitudes, even though it should still be plenty for most purposes of lateral
navigation. Vertical position would suffer more than horizontal position, but
vertical position is already much less reliable than horizontal position at
any latitude with GPS (the system is designed primarily for lateral
navigation).

Yep.

No it isn't. You won't notice any difference in sattelite coverage.

If you go much farther north than Iqaluit, the geographical moving map
(shorelines, towns, roads, etc) disappears, but all the Jepp data is
still there.

Excellent - that's what I was hoping to hear.

Thanks!

Hjow about watching your freakishly obese fingers when yjou're
mashing them at the keyboard?

Mx's statements are backed up by plenty of articles. It appears,
for some strange reason (the atmosphere), the timing between the
receiver and the satellite can fluctuate at higher latitudes.

I'll stop feeding the troll now. Sorry.

Bullsheit!

Mxboy was rattling his keyboard because he likes to hear himself talk. He
blathered nothing more than what Craig stated he already knew, and did
nothing to answer his question. How does it affect daily operations?
