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.

Maritime Education

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.

Project results in detail. Efficient port flow using the Port Activity App in the ports of Gävle and Rauma. Sharing time stamps making planning easier for all involved actors. Efficient ship Flow by using a Route distribution service helping pilots better plan meeting points in narrow fairways, saving some fuel but more importantly increasing safety.

Here is the latest version of the professional handbuch of "pilot Ladder Safety" for the rigging and the use of pilot ladders by Herman Broers from July 2021.

Pilotage is being able to navigate safely into and out of a harbour/anchorage/port knowing where you are at all times, where your hazards are and a safe route in/out. This is particularly useful if you are heading into somewhere new or a challenging/busy area – or both!

On February 9th, 2023 Unites States Coast guard issued a safety alert (04-22-CH1) in which attention is drawn to the correct positioning of handhold stanchions onboard of ships.

Great Lakes Pilot Eric Treece joined us in the Virtual Visitor Center for an interview about his career as a fleet captain and his experiences now as a pilot working aboard a variety of ships. In the course of the conversation, he shares some spectacular photos he has taken over the years. TECHNICAL NOTE: there are a few audio glitches we could not correct but it only impacts a few spots.
