0 a way of calculating the position of a ship or aircraft using only information about the direction and distance it has travelled from a known point
It goes without saying that mere dead reckoning, entirely unchecked by astronomical observations, would be insufficient for scientific purposes.
The distance which we traveled day by day was at first determined by dead reckoning, to be verified later by observations for latitude.
The position of the ship was found, and marked on the chart, and the "dead reckoning" compared with the result obtained by calculation.
We had been six days out without an observation, and our dead reckoning naturally was uncertain.
The main advantages of dead reckoning location are its low cost and its easy implementation and exploitation.
Dead reckoning is usually performed by odometry, which involves the integration of wheel rotation increments over time to estimate the position of a vehicle.
This experiment is an illustration of the drawback of dead reckoning.
