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.

When the bow thruster has been in operation for a while, pilots often notice that the ship not only turns but also gains speed. But why is this? Opinion by Capt. Hugues Cauvier.

A portable pilot unit (PPU) is a portable navigation aid system designed specifically for ship pilots, such as the SIRIUS series from TRENZ in Germany (www.trenz-ppu.com).

This video has been recut and edited by the creator Hugues Cauvier. Previously there were three episodes, which have now been combined into one.

We take a look at some of the dangerous ladder arrangements provided by ships when attempting to take maritime pilots on board. Our message is simple: if you are offered an unsafe or non-compliant ladder, do not board!

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.
