GPS does indeed work in the polar regions. In Google Images, search "GPS south pole" and you can observe the one souvenir obtainable at the South Pole Station, to wit: a photo of your hand held GPS reading S90 00 00.
I've looked into it. The last time I checked, its a $30K round trip, with no overnight stay. They fly you to the South Pole, you walk around for a bit, and you fly back. The souvenir photo is practically obligatory.

Lu, Is GPS navigation really available everywhere? In particular in the Polar regions? If not, what is the other reliable way of navigation in polar regions?

Emergency navigation was given as one possibility. I rather suspect that in the two examples given by Greg the explorer was using celestial as a primary means. That begs the question of "why?"

You would add this to the the question or this is a part of an answer? Do you know any people traveling in remote wilderness (on land) who are using Cel nav, or carry sextants, almanacs, etc.? I have never heard of such people in modern times. Alex. : http://fer3.com/arc/m2.aspx/Status-Celestial-Nav-2015-LuAbel-mar-2015-g30568
