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 video is an extract of some elements from lectures by Knud Benedict on "Simulation" as part of the seminars provided by the IALA World Wide Academy on the use of the "IALA Toolbox for Port & Waterway Risk Management".

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

Another great education video by Knud Benedict (Germany): Practical experiments for getting useful data for planning.

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.

Join the pilot crew on the water for a behind-the-scenes look at marine operations at Port of Cromarty Firth.
From early starts on the Firth to working alongside visiting vessels, the pilot crew play a key role in supporting safe marine movements in and out of the Port. This video captures the skill, experience and coordination involved in helping vessels arrive, depart and operate safely within the Cromarty Firth.
With deep, sheltered waters and a busy mix of cruise, energy and commercial...
