Finding your position and choosing a route are among the oldest technical problems in travel. The comparisons in this category trace how sailors, drivers, and hikers have answered them, from ink on paper and needles that point north to measurements taken from satellites.
Printed Maps vs GPS Navigation, Magnetic Compasses vs Smartphone Sensors, and Sextants vs Satellite Positioning all deal with the same two questions: where am I, and where should I go? The methods differ sharply in what they require from the user, how they fail, and how much skill they demand. Each article also notes what the older tool still does well when batteries run low or signals disappear.
The guiding question: How did the methods for working out where you are and which way to go change, and where do older tools still hold up?
