DEAD RECKONING

Dead reckoning is actually a very simple process to understand.(DISTANCE TRAVELED OVER A PERIOD OF TIME)Essentually all you are doing is estimating your current position based upon a previously determined one, sometimes called a fix, and advancing your position based upon a known or estimated speed over an elapsed period of time, by following a set course. While traditional methods of dead reckoning are no longer considered primary means of navigation, it is a very handy skill to understand when modern inertial navigation systems fail.By the way, these systems also depend upon dead reckoning and they are very widely used as you know.

Disadvantage Of Dead Reckoning

The disadvantage of dead reckoning is... Since new positions are calculated solely from previous positions the errors of the process are cumulative and the error in your known position grows with time. So in order to be as accurate as you possibly can you must do your best to stay on a true course.Using a compass is the best way to do this as you can see the radial (compass degree) you are following. There are other techniques that are quite dependable but not quite as precise as a compass.

This information is very useful if you were to become lost in the wilderness somewhere and all you had was a map of the area.To use this type of navigation you must have a map to plot your location. So no matter where you go please be sure to have a map of the area with you in preparation, should you ever find yourself in a survival situation.

Preperation is the key to it all!
