How GPS works? Trilateration explained

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.

This video is an extract of some elements from lectures by Knud Benedict on "Simulation" as part of the seminars provided by the IALA World Wide Academy on the use of the "IALA Toolbox for Port & Waterway Risk Management".

Stanchions therefore are an often-overlooked part of a pilot transfer arrangement and therefore I
want to give them more attention in this article. They proved to be the cause of a whole series of accidents, some of which were even fatal.

The term Automatic Identification System (AIS) refers to a radio system that improves the safety and guidance of vessel traffic by exchanging navigation and other vessel data.

Entrainement sur simulateur des pilotes du Havre-Fécamp : pilotage des barges transportant les embases gravitaires du champ éolien offshore de Fécamp. Plus de 500 H de formation et de travail préparatoire ont été nécessaires pour préparer ces opérations de pilotage portuaire exceptionnelles

This important topic is still underestimated in shipping! Can you trust your GPS? Your Galileo? Knowing where the ship is and where to sail next is the main task of navigating a ship and is commonly supported by using Global Navigation Satellite Systems (GNSS). But what happens if the GNSS gets intentionally disturbed?
