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 document aims to provide information to pilot organisations and/or competent pilotage authorities on the conduct of pilot transfer operations.

Technology group Wärtsilä will supply its latest simulator technology for a new maritime training centre in Finland.

There are many things in both our everyday and professional lives which we take for granted and never question the origins of, an example of this might be the IMPA recommended ‘pilot mark or pilot line’, which is sometimes seen on the side of vessels indicating where a vessels freeboard exceeds 9 metres.

Understanding the fundamentals of the pivot point is highly required for understanding the alteration of the courses. Pivot point is an imaginary point on the vessel which turns on a circular path on the perimeter of vessel’s turning circle when the vessel makes a turn. The knowledge about the position of the pivot point in a manoeuvring situation provides the ship handler with the information on the geometry of motion of the ship.

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.

Marine pilot Indrek Sülla (Eesti Loots) spotted dolphins in the waters of Kopli Bay, off the coast of Tallinn, a few days ago. This is a very special event in this region and so far north.

Lately there has been a considerable increase in opinions of seagoing ship´s masters complaining about pilotage services, expressed whether as LinkedIn articles and comments or in some reputable industry magazines.
