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.

"Person over board - all pilot boat crewmembers and pilots should be trained in recovery as realistic as possible. Don’t wait for a real emergency to find out that something doesn’t work as intended!"

A in-depth video explaining how DUKC® works.

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.

This research paper could be useful tool for marine pilots as well during the risk analysis of STS manoeuvrings. In light of the findings of the research, STS manoeuvres may be effectively planned in order to improve overall safety and avoid the unexpected incidents. On the other hand, there is a dearth of literature on STS operation. As a result, this work has a significant input on the current literature.

transfer of Marine Ship's Pilots by helicopter hoist is a demanding task.
Berthing means bringing a vessel to her berth until the ship is made fast. ... The berthing and unberthing manoeuvres require great knowledge and skill by the master, officers and the crew, as well as an excellent team-work with the rope-runners and the mooring party ashore
