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.

Port Revel is a ship handling training center for pilots, captains and officers. Unique in its kind, it allows to acquire new skills, to improve on different manned models at scale 1 / 25th.

Blog: https://www.merrimacins.com/understanding-and-preventing-tug-barge-risks/ Understanding and Preventing Tug & Barge Risks The maritime industry relies on tugboats and barges for a wide range of applications. Tugs are used to pilot vessels into and out of ports, while barges are used to transport bulk materials. The relationship between tugs and barges is critical, as most barges are not self-propelled and must rely on the skilled operation of a tug or tugs for propulsion. At Merrimac...

Ships have reported an increasing number of cases of significant GPS interference and jamming in recent months. The geographic areas with more than one reported incident include the eastern and central Mediterranean Sea, the Persian Gulf, and multiple Chinese ports.

What happens when GNSS fails? In maritime navigation, this isn’t a hypothetical scenario – it’s a growing risk. Spoofing, jamming, and GNSS outages are increasing, especially in the Baltic Sea region. A failure can cripple navigation systems – with potentially serious consequences.

Für Lotsen ist es der gefährlichste Moment in ihrem Berufsalltag: bei orkanartigen Böen von einem Frachtschiff eine Strickleiter herunterklettern und auf ein kleines Lotsenboot übersetzen. Mitte Januar 2023 ist ein Lotse bei Borkum ins Meer gefallen und kam mit Unterkühlungen ins Krankenhaus. Erst wenige Tage zuvor verstarb ein englischer Kollege bei diesem Manöver. Hafenlotse Gerhard Janßen und Seelotse Dominik Thieben machen sich für ihren Einsatz bereit. Bei Windstärke acht geht es mit...

An article by Arie Palmers highlights his collaboration with Multraship to develop a solution aimed at enhancing the safety of pilot boarding on harbor tugs, ultimately reducing delays.
