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.

In the spring of 2023, the IMO Sub-commission on Navigation, Communications and Search and Rescue (NCSR) may start a process of review and amendments to the SOLAS Ch V. reg 23

This video shows an introduction on the Spiral-Test-Manoeuvre and describes the procedure how to steer through this manoeuvre and measure the data needed. The results will be displayed in a characteristic diagram allowing to identify stable and unstable conditions and related, detailed information, e.g. spiral loop width and height, rudder angle of neutral effect. Samples of stable and unstable ship behaviour demonstrations will be shown by Fast Time Simulation using the SAMMON Planning tool.

This article describes the findings from two studies that utilised an integrated systems thinking framework to understand how pilots make decisions and what factors are perceived to influence their decisions.

Join us for a full exterior walkaround of the Norwegian pilot boat LOS 107 while she’s underway — bow to stern, wheelhouse to fenders. Real-time footage of a working pilot/launch at sea.

The Port of Milford Haven’s new pilot vessel has reached a key project milestone with a successful launch in the Netherlands, where the craft is currently under construction.
