Navigation (marine navigation) is the science, art, and technology concerned with the process of planning, executing, and monitoring the movement of a vessel from one point to another on water. It encompasses the determination of a vessel's present position, the calculation of the required course and speed to reach a destination, and the application of techniques and technologies to maintain the vessel on its intended path while avoiding hazards. This field integrates principles of position determination (including celestial, terrestrial, and satellite methods), dead reckoning, piloting, and the use of electronic systems such as radar, electronic charts, and communication networks (including wireless communications) to ensure safe and efficient transit within marine environments (marine systems), often involving human decision-making and interaction (human motion). Its significance lies in enabling reliable and secure maritime travel, trade, exploration, and other waterborne activities.
