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.

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!

SWATH and SWASH are interesting technologies that allow a vessel to sail much more calmly in high waves. A stable and calm position of the ship is especially important for pilot boarding.

We take a look at some of the dangerous ladder arrangements provided by ships when attempting to take maritime pilots on board. Our message is simple: if you are offered an unsafe or non-compliant ladder, do not board!

While in many western countries of the world, pilots there have already been preferentially vaccinated against COVID-19, pilots in other countries such as Malaysia are struggling to get vaccinated.
