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 movie belongs to the operation of ships with POD propellers and discusses the approach for using a vector model from only the pods’ thrust forces as resulting force to imagine the potential effect of the pods on manoeuvring motion.

Serkan Kahraman and Yusuf Zorba have published a new book for marine pilots. In this book, maritime pilots and shipmasters’ situational awareness levels have been analyzed using a bridge simulator system and the results have been obtained.

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...

At the A&R shipyard in Germany, the successful principle of SWATH boats was further developed in 2013: The SWASH principle allows sea-going, smaller and more economical boats.
