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.

Understanding the fundamentals of the pivot point is highly required for understanding the alteration of the courses. Pivot point is an imaginary point on the vessel which turns on a circular path on the perimeter of vessel’s turning circle when the vessel makes a turn. The knowledge about the position of the pivot point in a manoeuvring situation provides the ship handler with the information on the geometry of motion of the ship.

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.

In the pre-dawn hours and many other times of the day, local pilots safely guide cruise ships and cargo ships into BVI ports. The pilots provide local knowledge to the ships' captains to ensure safe arrivals and departures. In order to do this, it requires the pilot to climb from one moving vessel to the other. While this maneuver is taking place, the pilot vessel must maintain speed and stay parallel to the ship, allowing the pilot's safe transfer from one vessel to the other. They make...

According to a report in Daily Cargo News: Poseidon Sea Pilots will provide pilotage services for the PORT of Brisbane from January 1, 2022 and for a period of 10 years.
