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.

In the 62nd edition of Rumos Práticos the editors visited the Paranaguá and Antonina Pilotage Zone (Paraná-PR) to portray the challenges faced by the pilots in one of the largest port complexes in South America.

Specialized training for maritime pilots

In the video, Captain Pascal Rhéaume, pilot and member of the technical committee for the Corporation of Lower St-Lawrence Pilots, an active stakeholder...

Improvements to pilots’ situation awareness (SA) in maritime navigation are critical to reducing human errors, which have caused 75% to 96% of marine accidents over the last few years.

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...

SWATH and SWASH are interesting technologies that allow a vessel to sail much more calmly in high waves. A stable and calm position of the ship is especially important for pilot boarding.
