a system of navigation where the position of a ship is calculated without the use of any astronomical observation whatever.

The technique of determining position by computing distance traveled on a given course. Distance traveled is determined by multiplying speed by elapsed time.

The estimation of a ship's position from the distance according to the ship's log and the course steered by the compass, with corrections for currents and other factors, but without astronomical observations.

The basis of navigation in the Luftwaffe. With a knowledge of his aircraft's climb/cruise performance and given a forecast wind velocity and details of the track(s) to target, the navigator was able to calculate the headings to fly and time to reach his objective.

The calculation of a ship or aircraft's location by using the last recorded location and the measurement of its speed and drift. Dead reckoning is used when no other observations are possible.

A calculation of determining position by using course speed and last known position

From "deduced reckoning": a technique of navigation in which a plot is kept, starting at a known location (a fix) and, by careful observation of course and speed, the current position is deduced.

A method of navigation based on a known starting position, and tracking distance travelled and direction. [Section 5.5

an estimate based on little or no information

navigation without the aid of celestial observations

The method of calculating a shipâ€™s position by attempting to measure course and speed.

This positioning system allows you to visually judge your location according to landmarks, terrain, and estimated distances. This system may be accurate enough for some crude mapping programs, but it is generally not adequate for precision agriculture.

Determining position from a knowledge of heading, speed, and drift.

the practice of estimating a vessel's position by considering courses and distances made after departure from a known position

To plot a future position based on travel from a known position using speed, time and course

navigator's estimate of ship's position from the course steered and the distance run.

A navigational term. A way of determining your position by taking into account such factors as currents, wind speed, and your projected course and speed.

A navigation technique based on plotting courses and making calculations based on aircraft performance data and forecast winds aloft.

Dead reckoning is a method of navigation that involves calculating one's position by noting one's speed, the speed and direction of the wind, ocean currents, and compass directions. Dead reckoning was used by sailors like Columbus.

A plot of courses steered and distances traveled through the water.

A method of reducing the number of packets sent from a constantly moving object. If an object does not stray from it's current course, a packet need not be sent.

the process of predicting and fixing position by course, speed, and distance run.

Distance calculated from time on the water and estimated paddling speed.

A navigation method of determining position by making an estimate based on last known position, speed and currents.

A very simple method of using time and distance to navigate.

This is what a ship or airplane uses to pinpoint their location by using the last recorded location and how fast they are going. Dead reckoning is used when no other way of finding out your location is possible.

Calculating a boat's position based on its course, speed, and time run from a previous position.

A way of figuring your position based upon the influence of such things as currents and wind upon your projected course and anticipated speed.

A navigation method where position is estimated by measuring velocity, heading and time from the last known position.

a method of estimating field position based on forward speed, time of operation, implement width and number of passes.

You reckon correctly, or you are.

A method of determining position by making an educated guess based on last known position, speed and currents.

Derived from the more correct term deduced reckoning, is an estimated position by measuring the distance run based on speed and direction of travel from the last known position. Used when there are no visible landmarks.

This is a formula to determine where other players and objects are by calculating their positions based on the velocity and last location received. This information will be replaced when other players change velocity and send their new velocity.

A course leading directly to a reef.

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. While this method of navigation is no longer considered primary in ships, aircraft, automobiles, rail engines, and construction site engines (tunnels), it is still often used as a backup in case of failure of the electronic navigation systems. In studies of animal navigation, dead reckoning is more commonly (though not exclusively) known as path integration, and animals use it to estimate their current location based on the movements they made since their last known location.

Dead Reckoning is a 1947 Columbia motion picture starring Humphrey Bogart and Lizabeth Scott, directed by John Cromwell. This film noir drama/mystery was filmed in black-and-white.
