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.

Professor Patrick Hudson discusses safety culture and leadership.

Port Revel is used for shiphandling training of maritime pilots, masters and officers on a 5 ha lake with 11 manned model ships representing 20 vessels, and 4 tugs at scale 1:25 and DGPS tracking system. Instructors are former maritime pilots.
Training on the scale models provides experience that could never be gained on real ships for the simple reason that neither ship-owners nor local authorities would allow such risks to be taken. Scale models allow the shiphandler to make mistakes....

Serkan Kahraman and Yusuf Zorba have published a new book for marine pilots. In this book, maritime pilots and shipmasters’ situational awareness levels have been analyzed using a bridge simulator system and the results have been obtained.

Container ship CMA CGM MISSOURI ran aground in Suez Canal while transiting in southern direction, at around 0930 UTC Oct 14. As of 1745 UTC, probably refloated or moved, several Suez Canal tugs attending. Traffic probably suspended, but it’s not confirmed. No information on what caused grounding.

Safehaven Marine based in Ireland have just delivered a pilot vessel for operations at the Port of Berbera in
Somaliland, Africa. ‘Sanaag’ is one of Safehaven’s Interceptor 38 pilot vessels, at 11.9m LOA, a very capable design which proves economical to operate, yet capable of dealing with very rough seas and challenging boarding conditions when required.
