Manual Plotting sheets radar targets (a standard map (Maritime Science and STCW Standard)

Determining the movement of ships at sea and the ability to detect the direction and speed of ships At sea because of the difficulty in Ship maneuver on the sea surface And visual vision conditions that occur in a variety of conditions in the marine environment One of the most important factors is a safe and accident-free sailing at sea for ships.Therefore, navigation aid tools and devices have come to the aid of seafarers from the pattern of physical movement and the resulting rules Therefore, ensuring the correct operation and availability of information in all situations, such as device failure, makes Computational Principles of Ship Factors,It should be considered as the main and inseparable chapter of maritime knowledge by seafarers.In this paper, while examining the target factors in a standard way and by eliminating the computational factor of speed On a custom calculator to track how to track targets that are specific to high-speed vessels Express. Then do the plotting without using the sheet
