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.

"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.

The Nautical Institute (NI) and the International Maritime Pilots’ Association (IMPA) have been concerned for many years at the needlessly high rate of Pilot Ladder casualties. The NI is continuously reminded of the problem from its Members and through its Mariners’ Alerting and Reporting Scheme (MARS). The issue features frequently in our publications, and we recently dedicated an edition of our award winning magazine The Navigator to the topic, emphasising the importance of good...

Hooghly river Marine pilotage is one of the toughest and longest pilotage in the world,
pilots here face many challenges daily to enable safe passage of ships from bay of Bengal to the port of CALCUTTA and Haldia.
Pilot embarkation and disembarkation is a vital part , where the pilot climbs up or down a rope ladder ,if the free board is more than 9 meters then combination ladder is used it needs very good physical fitness practice and experience to safely embark and disembark from these...
