How GPS works? Trilateration explained

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.

The Australasian Marine Pilots Institute is presenting a webinar via Zoom about ports providing ECDIS routes and passage plans to ships as part of the pre-arrival process.

Kiel Pilots introducing Morild Interaktiv AS Virtual Reality Simulator for next-level manoeuvring training.

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.

How AIS Works - Operation of AIS

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.

AMSA: A pilot was seriously injured after losing balance when a large wave impacted the vessel at the same time as they stood up to remove their lifejacket while in the cabin.

This video explores the question of why ships are so difficult to manoeuvre in reverse.
