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.

MARIN has done model tests with a model of the msc Zoe in one of its test facilities, to find out what caused the msc Zoe to lose containers and how we can prevent this in the future.

Report by nC2 Engineering Consultancy at the University of Southampton on behalf of the International Maritime Pilots' Association (IMPA) to investigate the effectiveness and impact of different methods of securing pilot ladders in medium lengths in a laboratory-based project.

Over the past few years a number of pilot transfer accidents have occurred resulting from total failure of the side ropes, one school of thought is that the methods of securing a pilot ladder is a factor in such occurrences.

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.

Furetank turns a former office building into a maritime educational centre on Donsö outside Gothenburg: a state-of-the-art ship simulator complex for training, assessment and certification.

The IMPA Safety Campaign will take place from 16th to 30th May 2025. We encourage all maritime pilots to take part, as your contribution is essential to the success of the campaign!
