Dead reckoning (DR) is the process of estimating one's current position based upon a previously determined position, or fix, and advancing that position based upon measured velocity, time, heading, as well as the effect of currents or wind.
Dead reckoning is the navigation of a vehicles based on computations of position given an accurately known point of origin and measurements of speed, heading and elapsed time.
Dead reckoning is the process of estimating the position of an airplane or ship based solely on speed and direction of travel and time elapsed since the last known position (or fix).

  Gamasutra - Features - "Dead Reckoning: Latency Hiding for Networked Games" [09.19.00]
Dead reckoning is a form of replicated computing in that everyone participating in a game winds up simulating all the entities (typically vehicles) in the game, albeit at a coarse level of fidelity.
The basic notion of dead reckoning is agreement in advance on a set of algorithms that can be used by all player nodes to extrapolate the behavior of entities in the game, and an agreement on how far reality should be allowed to get from these extrapolation algorithms before a correction is issued.
Dead reckoning does not overwrite the received position, which may be needed for further dead reckoning at a later time.

 Dead Reckoning (1947)
Although it's not actually based on a book, John Cromwell's tautly-directed film noir owes more than a little of its plotting and characterization to earlier classic crime novels-turned-classic Bogart movies.
Even when things get ugly, this movie is always gorgeous to look at, thanks to the stunning use of shadows and light in Leo Tover's fl-and-white photography.
If you love Bogart and you like your film noir grim yet glamorous and over-the-top at times, DEAD RECKONING is well worth a rental; it's also making the rounds on cable on various Cinemax channels as of this writing.

 Columbus and dead reckoning navigation
Prior to the development of celestial navigation, sailors navigated by "deduced" (or "dead") reckoning, hereafter called DR. This was the method used by Columbus and most other sailors of his era.
The only way to get from Hispaniola to the Azores using Columbus's recorded courses and distances is to assume that he was using an uncorrected compass, and that he was pulled leftward by westerly magnetic variation in the Atlantic.
Applying the same assumptions to the westward voyage shows that Columbus must have been using dead reckoning rather than celestial navigation, because of the absence of course corrections.

 Medieval and Twentieth Century Navigation
While dead reckoning provided a measure of both latitude (distance north and south) and longitude (distance east and west), the celestial navigation technique shown above yielded a measure of latitude without the need for a log and the dead reckoning process.
While dead reckoning was suited to measuring location north and south or east and west, it proved useless over large distances where precision of several miles was needed.
Since dead reckoning was longitude and latitude independent, perhaps, an improved means of performing the process might achieve the prize.
