Dead reckoning is the process of estimating a global position of a vehicle by advancing a known position using course, speed, time and distance to be traveled. That is, in other words, figuring out where you momentarily are or where you will be at a certain time if you hold the speed, time and course you plan to travel.
А теперь этимология (я тихо торчу):
Dead reckoning is navigation without stellar observation.
With stellar observation, you are live, working with the stars and the movement of the planet.
With logs, compasses, clocks, but no sky, you are working dead
