    3 satellites for 2 dimensional space, 4 satellites gives you height as well (3 dimensional).

    your wristwatch gives you your fourth dimension ;-)

      GPS satelites are just fancy atomic wirstwatches hanging on Earth orbit

          but don’t they still only give you a 3 dimensional location?

          I’m trying to understand your question. They broadcast both their orbit parameters and their time.
