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.

"A performance assessment tool for maritime pilotage operations" - by Jørgen Ernstsen, Norway
When the ship is approaching or leaving a port, a local navigational expert, the pilot, is often provided for assisting the bridge team to safely and efficiently navigate the littoral waters.

Recorded presentation by All India Marine Pilots Association (AIMPA) on the topic "Pilot Ladder safety and Pilot Transfer procedures"

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.

This movie shows how to create the Characteristic Diagram for Wind effect on ships and limits of steerability under strong wind. It uses the previous demos made with the SAMMON Planning Software on turning tendency of ships on straight track and in turning motion.

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.
