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.

A look into the future of the ship's bridge with new technologies.

When a vessel navigates in confined waters, such as in a harbour or narrow channel, it is well known among experienced pilots that the ship handling is greatly affected by the hydrodynamic forces and moments acting between ship and bank or sidewall of the channel.

Tom Mellor - C​hairman of the IHO Electronic Navigational Chart Working Group (ENC WG) and Head of Digital Standards at the UKHO - explains what the IHO's ECDIS and ENC Standards mean.

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.

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.

Here’s a cool little video of the rough weather sea trails of ‘Port Láirge’ The Port of Waterford’s new Interceptor 48 pilot boat ready to be delivered next week. We had two days of rough weather, a Force 8 with 3.5m seas putting up some surf breakers over the Daunt and a second day with winds reaching Force 10 offshore, with 55kts of wind and 5m swells, allowing us to properly test her capabilities ensuring she's fully fit for purpose for the pilots and crew. Doing so we captured some...
