For this money they could give you a souvenir GPS,
not only a photo:-)

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.

that in the two examples given by Greg the explorer was using celestial as a
