Difference Between Dead Reckoning (DR) and Estimated Position (EP): How to Determine and Use Them

This video shows the difference between Dead Reckoning (DR) and Estimated Position (EP). It also shows how to determine them and which gives an accurate position. Dead Reckoning (DR) position is the position of the ship determined solely based on its last known position, course, and speed over a given period, without taking into account external factors such as wind, current, or other navigational influences. Estimated Position (EP) is the position determined from the DR position but adjusted for known external factors such as wind, and current. #navigation #passageplanning #seamanship #maritime #seafarer #seaman #bsmt #maritimestudents https://youtu.be/HQOd9Y8yOco
