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.

Before you, you see my third article on pilot boarding arrangements. After my two previous articles ‘1000 ways to secure a pilot ladder’ and ‘1000 ladders around’, I have received a lot of feedback and also questions to get deeper into the matter of combinations and embarkation platforms.

Join Great Lakes maritime historian and antiquarian Brendon Baillod as he discusses the restoration and conservation of a rare and very early 1865 Thompson's Great Lakes Coast Pilot. Early coast pilot books were kept on every schooner and steamer and Lakes and contain important details about the history of harbors, navigation, obstructions and shipwrecks on the Lakes. This 1865 Thompson's is among the rarest and also badly in need of stabilization. Enjoy this two part series where this...

When the bow thruster has been in operation for a while, pilots often notice that the ship not only turns but also gains speed. But why is this? Opinion by Capt. Hugues Cauvier.

This movie belongs to the operation of ships with POD propellers and discusses the approach for using a vector model from only the pods’ thrust forces as resulting force to imagine the potential effect of the pods on manoeuvring motion.
