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.

Training video III on the correct behaviour in case of man overboard

SAMMON Lecturing Video describing
"Pivot Point Demonstration"

SAMMON - the IDEAL tool to identify manoeuvring capabilities of a ship - SAMMON - learning the EFFECTIVE way

Case Study: An investigation into whether Port of Melbourne and major port user, ExxonMobil, could bring deeper drafted vessels into the channel.

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.

The Bollard Pull value, which can be interpreted as the maximum thrust that is developed for a specific amount of time by the propulsion systems of any vessel to the fullest , when it has zero speed in the forward direction, is the criterion that allows us to understand how suitable a tugboat is for a port maneuver or a towing operation.

MOSES (autoMated vessels and supply chain Optimisation for Sustainable short sEa Shipping) aims to improve the SSS component of the container supply chain through a series of innovations including innovative vessels and optimisation of logistics operations:

The IMPA safety campaign on pilot ladders has run for a long time now. In this document the results of the IMPA safety campaign have been analyzed from 2016 to 2020.
