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.

Theory on Wind drift will be shown together with demos using SAMMON planning on the effect of thrusters to have some effect on drift speed & direction

Two new locks were introduced in 2009 for training in the new Panama lock conditions with or without tug(s). This video shows the famous "piston effect" when entering the lock at an impressive speed of 10 knots with a high blockage factor.

Ships have reported an increasing number of cases of significant GPS interference and jamming in recent months. The geographic areas with more than one reported incident include the eastern and central Mediterranean Sea, the Persian Gulf, and multiple Chinese ports.

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 Swedish Maritime Administration is launching the world's first fully methanol-powered pilot boat today, It is one of the ministry's existing pilot boats, which has now been converted to test the new propellant. The work is part of the Swedish Maritime Administration's transition to a fossil-free fleet.

Connaissez vous le métier de pilote maritime ? Rencontre avec Gabriel Charpentier à Sète dans l'Hérault. Lorsque les navires de plus de 55 mètres arrivent dans un port, les pilotes maritimes prennent le relais du commandant. Ils ont la responsabilité de faire entrer ces gros bateaux par tous les temps. Lors d'une escale, ils sont les premiers à monter à bord en pleine mer sur une échelle de corde de neuf mètres.
