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.

GNSS interference has become a growing challenge in the Baltic Sea, affecting maritime navigation, aviation, and critical infrastructure. While numerous datasets and services, such as gpsjam.org, spoofing.skai-data-services.com, and flightradar24, report high-altitude GNSS interference based on ADS-B data, there is a significant lack of studies focusing on ground-level interference.

This study presents a novel decision support process for a pilot dispatching problem in the St. Lawrence River. It integrates a comprehensive set of time-based performance measures, including working time, waiting time, and skill level differences, to optimize fairness and operational efficiency in pilot dispatching.

After a thorough review, the GDWS has officially approved the Morild Ship&Bridge simulator for pilot training according to the German Pilot Training Decree (SeeLAuFV).

This movie belongs to the operation of ships with POD propellers and discusses the approach for using a vector model from only the pods’ thrust forces as resulting force to imagine the potential effect of the pods on manoeuvring motion.

Port of Townsville latest Mantaray HM ORC 173, along with all Port of Townsville’s pilot boat fleet is defined by the Pantocarene designed beak bow vessels that are the forefront of pilot vessel desingn worldwide.

When I was a deck officer back in the early nineties I worked on a ship that used to load grain at different ports along the Mississippi river. The name of the ship was Golden Hope, a 600 feet long dry bulk carrier with a 95 feet in beam. An average size vessel for those days' standards.
