How does GPS work?

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.

NAUTITEC as a maritime simulation and training centre offers various services for shipping companies, port authorities, captains and for pilots and tug crews.

Another very good explanatory video by Knud Benedict. Absolutely worth seeing.
Yaw Stability is an important element of Ships Manoeuvrability - both for course keeping and turning ability. This first video in a series explains the Basic Principles of stability in steady state equilibrium conditions and the forces / moments involved

To monitor the vessel’s progress, the pilot had set up his portable pilotage unit (PPU). He had connected the rate-of-turn generator to the vessel’s pilot plug and had set a variable range marker on the radar with a radius of 0.5 nm.

This movie belongs to the operation of ships with POD propellers and discusses the approach for using a vector model from only the pods’ thrust forces as resulting force to imagine the potential effect of the pods on manoeuvring motion.

Fathom Safety was established as a not for profit organisation dedicated to improving maritime pilot transfer safety. Here is a guide to pilot ladder rigging. We hope you like it!

It has been 1 month since the 1st case of coronavirus in the country. All airports were shut down, and mandatory confinement was issued 10 days ago. Nevertheless, Maritime shipping must continue (except for tourist related). The means that us pilots must continue with our duties despite the risks involved with all the ships' crews arriving from different countries. So we need to take all safety measures possible.
