Diploma in Terrestrial and Coastal Navigation - Second Assessment

Diploma in Terrestrial and Coastal Navigation - Course Assessment

This free online course outlines the importance of coastal navigation and aids used for estimating a vessel’s position.

Diploma in Terrestrial and Coastal Navigation

Since 2 000 B.C.E., sailors have been navigating the oceans. This course teaches you the planning and monitoring of marine passage using terrestrial and coastal navigation, which explains how to plan and fix a ship’s position at sea. We will outline the concept of the Earth’s axis passing through the north and south poles, the Earth’s equator, which maintains equidistant from the poles, and the polar axis from which you measure angle coordinates.
