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.

SWATH and SWASH are interesting technologies that allow a vessel to sail much more calmly in high waves. A stable and calm position of the ship is especially important for pilot boarding.

This is the recording of the presentation with the title:
“Digital Twins" as Key Maritime Technology Innovations for MET - and for Operation of Intelligent Ships
It was held at the MET Training Course by Shanghai Maritime University on Oct 27 2020 on the occasion of IMLA 40th anniversary

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.

This video shows an introduction on the Spiral-Test-Manoeuvre and describes the procedure how to steer through this manoeuvre and measure the data needed. The results will be displayed in a characteristic diagram allowing to identify stable and unstable conditions and related, detailed information, e.g. spiral loop width and height, rudder angle of neutral effect. Samples of stable and unstable ship behaviour demonstrations will be shown by Fast Time Simulation using the SAMMON Planning tool.

Risk Involved When Unmooring Operation on Deck

When you think about SWATH ships, remember seakeeping. Imagine gliding gently over waves. That serenity is what SWATH ships deliver. It comes at the price of several new design challenges. But for the right mission, a SWATH is worth it. Maybe the tradeoffs are right for you? Learn about the strengths and weaknesses of a SWATH.

The 160 pilots allotted to the PZ are distributed in eight pilot companies responsible for attending ships that seek the ports or terminals of Santana (AP), Munguba (PA), Santarém (PA), Trombetas (PA), Juruti (PA) and Itacoatiara (AM), as they sail upriver (against the current).
