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.

SWATH and SWASH are interesting technologies that allow a vessel to sail much more calmly in high waves. A stable and calm position of the ship is especially important for pilot boarding.

The Bollard Pull value, which can be interpreted as the maximum thrust that is developed for a specific amount of time by the propulsion systems of any vessel to the fullest , when it has zero speed in the forward direction, is the criterion that allows us to understand how suitable a tugboat is for a port maneuver or a towing operation.

Theory on Wind drift will be shown together with demos using SAMMON planning on the effect of thrusters to have some effect on drift speed & direction

As a part of the ISTLAB project the impact of external factors on pilots’ activities in a remote pilotage situation has been examined in Rauma.

This publication (2024) details the rules, regulations and procedures that should be followed when preparing for pilot embarkation and disembarkation. It includes relevant excerpts from SOLAS regulations and IMO resolutions.

This book investigates the science behind each component of manoeuvring a ship in confined waters, especially in port limits and the art to master it. Based on practical observations and analysis of each major and minor aspect of the manoeuvring of different types of vessels in different types of situations, this book put all relevant knowledge together for the reference of all concerned with pilotage and ship handling.

For the safety of maritime pilots
