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.

Manoeuvring large ships at close quarters and on shallow water is one of the most difficult aspects of shiphandling because of the complex hydraulic interactions depending on the ships' speeds, on the water depth and on lateral restrictions like in canals. Training is conducted both on meeting and on overtaking ships in shallow waters. This video shows how overtaking in a canal should be conducted: come in close to the stern and then move away from the bow that will be sucked towards your...

RightShip continues its webinar series on pilot ladder arrangements. On September 18th, they´re asking two marine pilots to share their first-hand perspectives on pilot ladder arrangement best practices.

Another video by Knud Benedict: This movie reveals some practical insight into regions of course stable / unstable conditions under wind. And I dare to say you can get some insight into other stability types and analogies, too!

Kiel Pilots introducing Morild Interaktiv AS Virtual Reality Simulator for next-level manoeuvring training

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...

The IMPA has published on 30th June 2020 a letter about crew exchange in times of corona. Read the letter here:

One of AMPI’s core missions is to advocate for the safety and well-being of marine pilots, and an essential part of that work is developing Position Statements.
