State-of-the-art navigation is not written in the stars.
A brief look at some history: The word “Navigation” is derived from the Latin. It means as much as the guidance of a ship. The task of helmsmanship is to guide ships, boats and yachts safely to the desired position. In this process it must be ensured that the current position can be determined at any time. It must also be possible to calculate the optimal route at any time.
The art of astronomical navigation was developed over 6000 years ago.
And until the mid-90s, most of the navigation work on board was still performed using a compass, sextant, log, sea chart, course triangle and a compass drawing tool. Only then did more and more highly technical and complex systems come into use, which made navigation on ships at sea safer.
