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.

At the 27 October 2020 meeting, the Board reviewed the SHPA grant request for a pilot ladder climbing training program.

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.

“Marine Pilotage – The Arabic book" by Ahmed Sati, Marine Pilot at P&O Maritime, is the first of its kind in Arabic language and specifically concerned with maritime pilotage, it is a reference book and introduction to the basics of the Marine Pilot's work for Arabic readers who are willing to take the challenge and join the force of Pilotage and to act as a refresher to the experienced Pilots who are practicing Pilotage in local or foreign organizations.

This video complements the earlier demonstration of wind effect on straight track and shows now wind effect on turning circles. It can be seen that during a turn under strong wind the ship reduces turning when it comes close to equilibrium on straight track - if the Wind-to-ship speed ratio is big enough then the ship even goes straight instead of turning. This is shown for three samples for Head, Stern wind and Beam wind. The turning can be increased if the ratio of Wind speed-to-ship...

This webinar is part of the Resilient Positioning Navigation and Timing Seminar Series.

The US Coast Guard has now issued "Marine Safety Information Bulletin 21-20" which repeats the recommendation for pilot transfer agreements.

With only 10 days of preparation time, NAUTITEC successfully executed a high-end simulation of the Odyssey`s river-passage on a scientific level and they are glad to have seen simulation become reality once again.
