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.

Theory on Wind drift will be shown together with demos using SAMMON planning on the effect of thrusters to have some effect on drift speed & direction

From that moment on I have been keeping a tally of the non compliant boarding arrangements I see in front of me on a daily base, and off course I participate in the annual safety campaign, conducted by IMPA each october.

On the occasion of the Maritime Safety Week (July 4-10), UK MAIB’s inspector Bill Evans refers to the issue of unsafe pilot ladders, a concern that has been regularly voiced by the industry.

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.

The Bollard Pull value, which can be interpreted as the maximum thrust that is developed for a specific amount of time by the propulsion systems of any vessel to the fullest , when it has zero speed in the forward direction, is the criterion that allows us to understand how suitable a tugboat is for a port maneuver or a towing operation.

A more unique angle regarding freighter departures; I was able to film the routine disembarking of one of our local ship captains and officers after piloting Solina out of the harbor. This is a required procedure, as per US Maritime Laws, all international freighters must be piloted in and out of a US harbor by a US Captain. Here we have out local pilot vessel Sea Bear running up alongside the Solina to allow the two officers to depart the freighter before she heads out across Lake Superior
