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.

Short demonstration highlighting key features of the VR Marine Pilot training simulation LWA Solutions have delivered for the Ports of Auckland.
Editors Note (4th July 2020):
This video shows the fantastic possibilities of virtual reality technology. Wonderful demo by Ports of Auckland. In respect for doing this amazing experiment. If somebody knows more about this or other interesting similar projects please leave a comment below and help us to complete information about virtual reality...

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.

At the A&R shipyard in Germany, the successful principle of SWATH boats was further developed in 2013: The SWASH principle allows sea-going, smaller and more economical boats.

Manoeuvring large ships at close quarters and on shallow water is one of the most difficult aspects of shiphandling because of the complex hydraulic interactions depending on the ships' speeds, on the water depth and on lateral restrictions like in canals. Training is conducted both on meeting and on overtaking ships in shallow waters. This video shows how overtaking in a canal can easily fail.

Tug power has increased considerably over recent decades. Today, some ship handling tugs have a bollard pull of more than 100 tons. In addition, high tug power can be installed in ever smaller compact hulls.
