Yes, have heard of it as a survival tool. But - as far as heavenly bodies go - unless you should happen to be flying around with a copy of the Admiraltys H.O.249, you would be limited to measuring bodies that you know stuff about. The north star is usefull for finding your lattitude. Having a watch running UTC, your lattitude and a sunrise/sunset table, you would be able to locate your approximate longtitude by timing local sunrise (assuming you had already determined your lattitude).
