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.

A study of increasing competition in ports and the underlying pressure to improve port performance. This thesis is the final deliverable for the completion of the degree of Master of Science in Transport, Infrastructure and Logistics (TIL) at the faculty of Civil Engineering and Geo-sciences at the Delft University of Technology.

London Pilots (PLA) have issued an excellent quick reference guide for Pilot Transfer arrangements, which can be used for pilots as well as ship’s crews. Please take not of this document and if you can, try to incorporate it into your procedures.

When a vessel navigates in confined waters, such as in a harbour or narrow channel, it is well known among experienced pilots that the ship handling is greatly affected by the hydrodynamic forces and moments acting between ship and bank or sidewall of the channel.

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.

Through the years, the Dutch Pilots have developed a system of selection, initial education and continual professional training. What is the current state of affairs?
