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.

Today, we embark on a voyage into the intricate world of ship types. From massive container ships to nimble oil tankers, we'll explore the unique challenges each vessel presents.

Wind Balance on straight track - using SAMMON to learn the theory and the effect of rudder and drift to reach the balance in steady state equilibrium conditions on straight track. Limits of steerability will be shown and how turn under strong wind.

The latest MS Amlin Marine circular, compiled by theTechnical Loss Prevention Consultant Peter van der Kroft, focuses on the importance of pilot safety in marine navigation.

To minimize the risk of a vessel allision with a terminal gantry crane, the American Harbor and Docking Pilots Association recommends that all terminal operators with gantry cranes adopt the following Best Practices.
