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!

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). -- Transpose mxsmanic and gmail to reach me by e-mail.
