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.

On 1st April 2022 Brazil Pilots - Praticagem do Brasil - will organize a webinar about dangerous ladder with speaker Arie Palmers.

When a vessel navigates in confined waters, such as in a harbour or narrow channel, it is well known among experienced pilots that the ship handling is greatly affected by the hydrodynamic forces and moments acting between ship and bank or sidewall of the channel.

Finland's first remote pilotage of a cargo ship will take place at the beginning of 2022. The first remote pilotage permits may be issued in 2025.

This video explores the question of why ships are so difficult to manoeuvre in reverse.

The international pilots association Impa is sounding the alarm about unsafe pilot ladders. According to the pilots, a worldwide survey has shown that access to the ship via the pilot's ladder often does not comply with the regulations.
