What is the main function of Dead Reckoning in navigation?

• A. To estimate a position using maps
• B. To calculate vehicle speed
• C. To determine one's current location based on a starting point
• D. To find landmarks using coordinates

Answer: (C)

Dead Reckoning is a navigation technique that determines one's current location based on a previously known position (the starting point) and ongoing travel data such as speed, direction, and time. This approach is essential when other navigational aids, such as GPS or celestial navigation, are not available. By using dead reckoning, navigators can estimate their current position by continuously updating it and calculating how far and in what direction they have traveled from the known position. This method allows for effective navigation, particularly in situations where immediate reference points may not be visible.
