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.

In fact, the pivot point that we “see” is a trick of the eye, it looks like the ship is rotating about this point but in fact it is elsewhere, a point that you cannot see.

Practical samples for manoeuvres for ships going astern - as Stern-First-Method SFM. Introduction using as sample from the Master Thesis by Karel Wiegert for an arrival manoeuvre of a cruise vessel in Southampton port with a Twin-screw vessel under strong current. The same manoeuvre with the same ship model was used to show the advantage of Fast Time Simulation FTS using the SAMMON Planning Tool. This goes much faster than the manoeuvres in the real time simulator - and it can even be...

A study of increasing competition in ports and the underlying pressure to improve port performance. This thesis is the final deliverable for the completion of the degree of Master of Science in Transport, Infrastructure and Logistics (TIL) at the faculty of Civil Engineering and Geo-sciences at the Delft University of Technology.

This video explains the impact of lateral resistance on the turning circle of a vessel using animations. The video explains the term lateral resistance, shows an example of its impact on the turning circle and its associated aspects (advance, transfer, tactical diameter and drift angle).
Contents of this video will benefit mariners preparing for exams (written and oral examinations).
