Shoreline map navigation errors

What is it about?

Currently, satellite navigation systems such as GPS, GLONASS, Galileo and others are widespread. However, in the case of high requirements for the reliability of navigation, such systems are of little use, since they are easily suppressed by electronic means. Therefore, alternative navigation tools are developing, using, in particular, technical vision. The most important requirement for navigation systems is the accuracy of navigation. The article is devoted to the analysis of the accuracy of navigation on the image of the coastlines of the seas and oceans.

Why is it important?

The problem is that the accuracy of optical navigation depends on a large number of factors, in particular, on the shape of the observed shoreline, observation angle, distance, the accuracy of localization of each section of the shoreline, and so on. Thus, each cycle of measuring the coordinates of an object is characterized by its own error matrix. This error matrix must be taken into account when filtering the measurement results. Some “average” error values ​​cannot be used.
