Dead Reckoning

Dead reckoning is a navigation method used to estimate one's current position based on a previously known location. It involves calculating distance traveled and direction taken, considering factors like speed and time, without relying on external references. For example, if you start from point A and know you walked 3 miles east and then 4 miles north, you can deduce your approximate position relative to point A. While useful, dead reckoning can be less accurate over time due to factors like wind or currents, which is why it's often combined with other navigation methods.

    Dead reckoning is a navigation method used to estimate an object's current position based on its last known location, speed, direction, and time traveled. Essentially, it involves calculating where you’ve been and how fast you’re moving to predict where you are now. This technique is commonly used in aviation and maritime navigation, especially when other navigation aids (like GPS) are unavailable. However, it relies on accurately maintaining speed and direction, as any errors can lead to significant inaccuracies over time.
