Does GPS work in remote/deserted area in the US?

Question

Such as Southern Utah, Grand Canyon, Death Valley...

Answer 1

Because your GPS is communicating with satellites overhead, your geographical location on the planet does not make much of a difference.

The topology of the specific location that you are in DOES make a big difference however. Best reception occurs in open 'big sky' areas like open fields or hill and mountain tops. You get poorer reception in valleys, canyons, and - too a lesser degree - in areas of heavy tree cover.

This can be important in much of the canyon areas of the southwest (southern Utah, Grand Canyon) where the deep canyons do make GPS reception more difficult and there are large dead zone areas.

I recently purchased a Garmin 60CSx GPS with a new software technology that Garmin claims gets much better reception in canyons. I was skeptical at first, but after several trials in Grand Canyon and Grand Gulch (Utah), I was quite impressed (only lost reception in the most narrow places).

Answer 2

So long as you are in clear view of at least two or three satellites it will work.

Answer 3

if'n it has got sky over it, it will work!
