In Africa we had ONC Charts, A Michlien Map, and a compass. You figured out the coordinates off the map and then walk 50 yards from the car and took a reading. We also learned to shoot stars at night with a Surplus Yougslavian Army sextant. Pointing out you YQYQLALALOLO was important since there were no roads and lots of tracks. The old Military training was helpful. You arrived at an Oasis and asked directions to the next Oasis. "100 clicks at 180 degrees then turn left 276 and drive 50 clicks and turn at the metal rod..." Piece of cake.
