If the earth is flat, how did the navigators of sailing ships work with a sextant? How does gps work?

Why would you think a sextant wouldnt work on a flat earth?

It measures angle from celestial body to horizon.

I need to get a sextant for an experiment. if I pick any latitude, say x, then on a globe if I travel directly west for any given distance, I should never leave that latitude. However if the earth is flat, I should end up traveling traveling tangentially to x and change latitude. Right? Obviously I wouldn't rely on GPS for this
