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.

This video complements the earlier demonstration of wind effect on straight track and shows now wind effect on turning circles. It can be seen that during a turn under strong wind the ship reduces turning when it comes close to equilibrium on straight track - if the Wind-to-ship speed ratio is big enough then the ship even goes straight instead of turning. This is shown for three samples for Head, Stern wind and Beam wind. The turning can be increased if the ratio of Wind speed-to-ship...

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.

“The world of hydrography is going digital and the S-100 standard is an essential component of that move.” See how the Canadian Hydrographic Service has led Canada to become one of the first countries in the world to start using the S-100 standard, and how implementing these standards will benefit Canadians through increased safe navigation in Canadian waters.

Shiphandling discussion about meeting and overtaking situations in a close quarters situation where hydrodynamic effects will come into play between ships. The lecture continues and discusses Bank Effect.
