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.

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.

GNSS interference has become a growing challenge in the Baltic Sea, affecting maritime navigation, aviation, and critical infrastructure. While numerous datasets and services, such as gpsjam.org, spoofing.skai-data-services.com, and flightradar24, report high-altitude GNSS interference based on ADS-B data, there is a significant lack of studies focusing on ground-level interference.

"Person over board - all pilot boat crewmembers and pilots should be trained in recovery as realistic as possible. Don’t wait for a real emergency to find out that something doesn’t work as intended!"

Associated British Ports (ABP) will upgrade its recently acquired pilot launches to enhance safety, effectiveness, and sustainability, incorporating feedback from its pilots and marine teams. The program will expand the fleet of larger vessels from three to five, replace older models, and improve seakeeping, crew safety, comfort, handling, fuel efficiency, and emissions reduction.

Here's a nice little video of sea trials during the recent unseasonal storm we had last month, which produced some pretty rough conditions at the entrance to Cork Harbour. We managed to capture some nice footage of the Barracuda and Thunder Child II on the day.
