How GPS works? Trilateration explained

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.

In this movie the efficiency of two different pod operation strategies is compared: With azimuth propeller ships the Pods can be used in two ways to control the speed, e.g. for speed reduction: 1. by adjusting the engine orders, e.g. by reducing the RPMs to get lower speed - this means to drive the ship in the same conventional way as for twin screw vessels, 2. by turning both pods either in- or outward (TOE-IN or TOE-OUT) to reduce the forward thrust and therefore reducing the speed – the...

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.

"Person over board - all pilot boat crewmembers and pilots should be trained in recovery as realistic as possible. Don’t wait for a real emergency to find out that something doesn’t work as intended!"

This document aims to provide information to pilot organisations and/or competent pilotage authorities on the conduct of pilot transfer operations.

Training video II on the correct behaviour in case of man overboard

The CMA CGM JACQUES SAADE, our new flagship, is the first of a series of nine sister ships, a homogeneous LNG-powered fleet.
An innovation-packed feat, a pioneering choice that aims at preserving air quality.
The result of 7 years of research and development.
More than a flagship, a vision.

With approval from the Danish Emergency Management Agency, DanPilot and Danelec are now initiating a test program for remote pilotage – the first of its kind in the world.
