Marine navigation

Definition

Marine navigation is the process of planning and directing the movement of vessels through water, ensuring safe and efficient travel from one point to another. This involves understanding the position of the vessel relative to landmarks, using various tools and technologies to maintain a proper course, and avoiding hazards such as underwater obstacles. Effective marine navigation is crucial for underwater robotics, as it allows for accurate positioning and operation in challenging environments.
