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.

In December 2022, a week-long innovation camp was organized in Turku Finland, in which 16 students from the University of Turku, Novia University of Applied Sciences and five different universities in Singapore participated. Pilotage operators Finnpilot from Finland and PSA Marine from Singapore acted as industry partners.

Maritime pilots trace the roots of their profession back to the ancient Greeks and Romans when incoming ship captains employed experienced local fisherman to guide their merchant vessels safely into port. It’s a legacy of skill, strength, and sharp wits, and our Houston Pilots (“Pilots”) have been meeting vessels at Galveston’s bar to carry on these proud traditions for just shy of 100 years.

Improvements to pilots’ situation awareness (SA) in maritime navigation are critical to reducing human errors, which have caused 75% to 96% of marine accidents over the last few years.

It has been exactly one year ago that a pilot from Sandy Hook (New York), Dennis Sherwood, died in the line of duty while attempting to board the container vessel Maersk Kensington.
What has happened since then? Has safety been improved for the pilots?

The General Company for Ports of Iraq (GCPI), a port operating company under the Iraqi Ministry of Transport, recently began operating a new catamaran pilot station vessel built by Colombo Dockyard (CDPLC) of Sri Lanka.
