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.

Shipping has evolved significantly over the years. Research in maritime safety and operations over the past few decades has been intensive and has resulted in significant improvements.

The latest summary from PTR Holland on the subject of pilot ladders. Here is the most important information on maintenance, use and replacement & insepection record book.

This video has already been published for the first time in 2020. Please also note the second, more recent video in the appendix. This physical ladder simulator was designed for crew training in the ladder arrangement and for all the users especially for pilots.

The European Tugowners Association in collaboration with the European Maritime Pilots Association has produced this informative video on efficient and safe towage operations. These guidelines address the main factors affecting the safety of harbour towage operations such as good communications between pilots, ship captains and tugmasters.

Today I will discuss a very simple and useful practical trick often used by pilots.

When we have to berth a vessel with small clearances forward and aft (say 20 to 25 mtr fwd and aft) it is very essential that you are able to estimate your position. Now most of the time you have a berthing supervisor on jetty who will help you with position.

Despite clear regulations and regular maintenance requirements, safety often falls by the wayside, as the current example of a bulk carrier vividly demonstrates.
