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 article was published some time ago but is still up to date: The study focuses on maritime pilotage in seven European countries and analyzes the level of job satisfaction and its predictors.

Lack of standard user interfaces across bridge equipment is a major concern for maritime safety. Pilots are in a unique position, as they are constantly exposed to new and differing bridge working environments, equipment, interface designs and combinations of systems.

Using pictures and sketches, this video finally explains the difference between gross tonnage (GRT) and net tonnage (NRT); the ship spaces that are included/excluded in their calculation; and the importance of these terms to ship owners.
Contents of this video will benefit mariners preparing for exams (written and oral examinations).

Maersk will begin implementation of an innovation called Snap Back Arrestor (SBA) ropes on the mooring lines used to hold vessels in place while docked in port for loading and unloading. Mooring is one of the most dangerous aspects of port and vessel operations.
