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.

Operators and supervisors of the operations center (atalaia) of Praticagem da Barra do Rio Grande participated in an update course in online and face-to-face mode.

"There is no good operation without recurrent training with good tools", says pilotage operational director, practical Bernardo Ramos

Thanks to Jacqui Kenyon, Chevi King and Kate Delisky for joining Jeanine Drummond on this webinar to discuss their careers and pathways into marine pilotage. The audience was a great mix of experienced marine pilots and newer maritime industry participants, as well as school aged children, with people joining us from Australia and overseas. It was an opportunity to create greater awareness of the maritime industry, and the important role marine pilotage plays in protecting our port...

At Humber Maritime College we have state-of-the-art marine simulators to teach our Merchant Navy cadets in an environment close to reality, preparing them for a career at sea.

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...

The term Automatic Identification System (AIS) refers to a radio system that improves the safety and guidance of vessel traffic by exchanging navigation and other vessel data.
