How does GPS work?

Of course, as a Nautical Specialist, I also deal with the international discussion on the advantages and disadvantages of satellite-based navigation, e-navigation and conventional terrestrial and astronomical navigation.

In my announced sequel, the second part of GPS, it is primarily about the technical and physical operational and functional limitations to which GPS is subject. These limitations, in part, have serious implications for the accuracy of GPS, and even go as far as limiting the functionality of GPS in its functions or even making it impossible. In doing so,

The vulnerability of GNSS in shore-based use is definitely different and to be regarded as much more risky than on the high seas.

This document aims to provide information to pilot organisations and/or competent pilotage authorities on the conduct of pilot transfer operations.

Recently, Herman Broers launched the website PilotladderSafety.com.
This website’s goal is to increase pilot ladder safety by showing good practice examples regarding the rigging and use of pilot ladder arrangements . Do it right the first time!

Understanding the fundamentals of the pivot point is highly required for understanding the alteration of the courses. Pivot point is an imaginary point on the vessel which turns on a circular path on the perimeter of vessel’s turning circle when the vessel makes a turn. The knowledge about the position of the pivot point in a manoeuvring situation provides the ship handler with the information on the geometry of motion of the ship.

Another great education video by Knud Benedict (Germany): Practical experiments for getting useful data for planning.

This video explores the question of why ships are so difficult to manoeuvre in reverse.
